Wood, tons of wood screws, different sizes, depends on your design, plexiglass sheet for making the window. Other items that you see in the photos and you might need, depends on your design

Computer items you need

_______________________

Mainboard that supports several GPU. CPU, GPU (as many as you can buy, fastest that you can buy), hard disk, power supply, monitor, mouse. You know what you need if you have built computers before. The mainboard is the key here. it must support several GPU cards. I use this machine for cryptocurrency mining and for ANN Artificial Neural Network using parallel processing of the GPUs for training the brain of our robots. if you are not into a.i. you can use your machine for mining, so it will cover its costs after a while. and you need to buy an airconditioning machine. it is a heavy thing. I bought an AKAI 5 KW AC machine. It makes the case very cool and makes the computer very happy.

GPU Clock

_________________

Many people overclock their GPU to get a few cents more when they are mining cryptocurrencies. This is a bad policy. This will stress your expensive GPU and kills it sooner than its natural happy life. This GPU (1080) according to the specs of the factory can go up to 1797 MHz. When you run miners, they push it to its limit. If I leave them alone, they push the GPUs to 1835 MHz. No good. So, I UNDER-clock the GPUs. do not do overclock. I reduce the clock by 120 MHz. So, when the miner is pushing it, it goes max to 1797 MHz. A happy GPU lives long. Also, I do not overclock the CPU. It is way faster than anything I ask it to do. And I do not use CPU for mining. It is a disgrace to make 2.6 Billion transistors (i7 CPU) run around for a few cents a day. Always when the GPUs are mining CPU is doing something else, like video editing or image processing.

In the previous step we saw, this machine has 39,000,000,000 transistors. We start with a love letter for them and their hard work. These 39 billion people are working hard. GPUTEMP program
keeps track of the temperature. It is like an EEG graph. When you know your beloved well, you know what she is thinking about by monitoring her EEG.

(Claymore) is a mining software. (Dagger Hashimoto) is an algorithm for mining Ethereum (ETH). T-Rex is another mio=ning software. (Kawpow) is an algorithm for mining RVN coins.

A multi-coin, multi-algorithm miner is used for choosing which coin is more profitable at each time. I use (nicehash) these days. There are many other programs as well. Note: I manually choose which mining program to run and which algorithm to be used for mining which coin. I do not leave it to (nicehash) to decide. You can choose your parameters in their GUI easily. If you leave it to their program (or any other multi mining multi pool program), they will mess with your GPU and push it too much. So you need to constantly reduce and increase the clock or else they cook your GPUs. I use whattomine.com and decide what to mine and choose the mining software and keep the clock unchanged. So it does not go above the max 1797 MHz.

This is version one. It is upgraded to the gas cooling machine. In this version, we have two large fans (50 cm diameter each). They are installed in parallel to take the air from outside and push it to the blue tube. An air filter is installed in the entrance of the airflow on the case, at the end of the orange hose that is air input.

Replacing the air filters every week. Their color was changed from white to dark gray. Because of the intensity of those two large fans, a huge amount of air was flowing through the filters to the machine and out. Air filters were about 1.5 cm thick. I had a few sets of them. I was replacing one. Washing it and in a couple of days, it was dry and ready to be reused.

In this photo, you see GPUs are installed vertically. Airflow is from the bottom of the photo to the top of the photo. On the left side, you see the water cooler radiator and two fans for the CPU.

An air conditioning machine is used. The indoor unit is installed inside the case. The outdoor unit is installed outside the case. The case is airtight and has no holes.

a - The rig is on top of the floating plate. The floating plate is hanging on four thick copper strings. Strings do not touch the wooden case. This is for preventing the vibration of the air conditioning machine to transfer to the computer. With a structure that you see in the next photos, you see that the floating plate is connected directly to the floor and does not touch the case at all.

b - strings

c- indoor unit or the air conditioning machine.

d- the door of the case is sealed by a sort of foam, matt, yoga matt material to prevent airflow. When the door is closed inside the case has no connection to the outside. All holes are sealed.

You need a whiteboard to design. measure. draw. erase. measure again. change. until it is correct and perfect. then cut the wood. measurements are related to the size of your cards. this structure that you see is a good point to start. if you do not have a whiteboard, you certainly need a ruler, pencil, paper, and eraser. pencil, not pen.

When you build your rig frame, do all your measurements twice before cutting the wood. Here on the left side, I made a couple of bases for the power supplies. So, there is space under them for their fan airflow. Then rig is put on top of the floating plate. The floating plate is hanged by the strings. There is a metal structure outside the case that keeps the strings. you see them in the next photos.

There are many free apps for iPad and iPhone to show you horizontal and vertical levels. or you can use a mechanical level device. buy it from a hardware tool store. I used the iPad app that to make sure strings are equal in size, so the floating plate is horizontal. I fixed the top of the strings on the structure that is outside of the case and adjusted their length from the other side that is inside the case. then tightened the bolt. You see a large wooden washer with a nut and bolt at the end of each string in the previous photo.

Parts before assembly. GPUs and GPU risers. Mainboard. CPU is connected to the watercooler and radiator. Be cautious about the electrostatic charge. It kills your boards and cards. Always connect a long wire to the earth hole of the electric socket on the wall and another side of that connected to your wrist. GPU Riser is an electronic device that is connected to the GPU from one side and with wire to the mainboard on the other side. so, you can move the GPUs up for more airflow. Do not put several GPU in the mainboard, even if your boards allow it. they do not get cool enough. They will be cooked and you waste thousands of dollars. Using the Riser is a must.

Two power supplies are used. Each one is 1250 watts. One is for the mainboard and hard disks. Another one is for GPUs. Each 1080 GPU eats about 180 watts. So, 1250 W for five of them is good enough. Sometimes I use the computer as it is without the GPUs. Not mining. Just doing other tasks. In this case, I turn off the power supply of GPUs and only turn on the main power supply. But airconditioning power always must be turned on. In this case, the big fan of the outdoor unit of the airconditioning machine does not turn on so often because GPUs are not on and the case does not become warm too much. CPU does not make too much heat.

a - Hings of the door of the case are connected at the bottom of the case. You need an electric screwdriver for 8 screws that closes the door. Takes a minute to open and close the door. But this is not something that you do often. When everything is working you do not need to open and close the case month after month.

b - The CPU has a water cooling circuit with a radiator and two fans.

REPEAT - IMPORTANT - long wire, connected to the EARTH on the electricity socket on the wall and other side connected to your wrist, while assembling these things. the electrostatic charge will kill them easily.

There is a window made with plexiglass. It is a double layer window. There is 1 CM gap between two layers to preserve the cool inside. This is not necessary, but it is cool to see them working. And the thermometer to show inside temp is on the left side of the window.

Also at the top of the case, you see the entrance of the strings. Two horizontal metal pipes are on top of the left side and right side structures. Strings are connected to the metal pipes. There is a hole on top of the case. The string goes inside the case and is surrounded by those green foam, plastic sheets. This will seal the hole for air. And the string is not touching the wooden case. Therefore the horizontal plate is completely hanging on the strings and not absorbing any vibration from the case. The indoor unit of the air conditioning machine is connected to the case. It does make some vibration but its vibration is not transferred to the computer. The bigger vibration comes from the outdoor unit. In the next photos, you see how its vibration is also isolated and is not transferred to the case.

a - You see the big box under the wooden case. It is the outdoor unit of the airconditioning machine. The blue hose is moving the air from the fan to the outside.

b - blue air hose

c - UPS uninterrupted power supply. This is not big enough for the mining machine. It is used for the server hosting brain of our robots. It keeps the computer alive for 15 minutes if the main power stops.

On the right side of the orange computer case, you see the vertical structure. Two metal pipes are connected to this. It is for keeping the horizontal plate inside the case to hang on the wires and not touching the case. For isolating the vibration of the AC machine.

Double layered plexiglass window.

a - inside thermometer shows 9.5 degrees.

b - AC is set to a 16-degree centigrade but inside the box goes lower than that.

c - the indoor unit of the AC machine.

d - water cooler radiator of the CPU

a - a USB extension cord for connecting USB devices. No need
to open the door of the case.

b - two copper pipes connecting the indoor unit to the outdoor unit of the AC machine. They are isolated by some foam wrap and plastic tape for conserving the cool.

c- a plastic pipe to carry the condensation water out. This is never used. inside the case has limited space and is dry. There is no airflow between the inside and outside of the case. so there is not humidity and condensation there. but if you install an AC machine in your room, you need this pipe.

d- monitor shows it is mining

e - the outdoor unit of the AC machine

f,g,h, I - These nuts and bolts are connecting the indoor unit of the AC machine to the wall of the case.

a - a heavy concrete base is keeping the aluminum structure.
one on each side. This is for the floating plate. The floating plate is inside the case. It is hanging on strings. The computer is on top of that. This structure guarantees that the weight of the computer is transferred directly on the floor and it is not touching the case. Therefore vibrations caused by the AC-machine is not transferred to the computer.

b - a large wooden block is used. The whole case is on top of that. There are four of them. We have one block in each corner. This is used for keeping the wheels alive. There are four wheels connected to the bottom of the case. They are used for moving it around if necessary. this thing is very heavy. It needs wheels. But we do not want to keep the whole heavy structure always pushing on the wheels. So, When it is in its permanent location I use a car jack and move it two cm up, and put wood blocks under it. So, wheels are not touching the ground and not carrying the weight.

c- airflow hose. it carries the warm air to the outside window.

a - The floating plate inside the case is connected to
strings. strings are connected to the metal pipes. pipes are on top of the aluminum structure that carries the weight of the computer to the ground. And the computer is not touching the case.

b- metal pipes. These pipes keep the strings. strings keep the floating plate.

a - strings are going through the metal pipe and connecting to the wood on top of the metal pipes

b - string goes inside the case in the hole on the wood. the hole is isolated by the foam sheet. Therefore string is not touching the case and the hole is sealed for airflow.

c - string is connected to the wood with a washer and a wood screw. wood is on top of two metal pipes.

a - four large woodblocks. the whole case is on top of them on the floor.

b - four wheels are connected to the bottom of the case. two of them are fixed on one side. the other two can move around. I bought a wheelbarrow and disassembled it and connected its wheel structure under the case. So I can drive the case left and right. Go to a tool shop store and see how a wheelbarrow works. No need to describe it here. Search for this keyword: garden cart with four wheels.

c- four concrete blocks are under the base of the case. The outdoor AC unit is not touching the base of the case. It is on top of these blocks. This is for isolating the vibration of the AC unit to the case. vibration is transferred directly to the floor. The next photo shows how it works.

a - look at the heavy screw and nut and bolt. it is connected to the base of the AC unit. this is a heavy unit. Four of them are used. Each side has one. the screw is going through a hole. the screw is on top of the concrete block. Therefore bottom of the AC unit is 2 CM above the wooden floor of the case. The weight and vibration of the AC unit are transferred to the screws, to the concrete block on the case to the floor. So, the AC unit is not touching the case. This is for operation time. If I want to move the machine to another place, then, I open the crews, and the AC unit will sit on the wooden floor. Then tighten the screws from the other side, from the bottom of the floor and it is connected tightly to the floor. and the machine will be moved to a new place if necessary. Then reverse the process and move it up 2 cm with the crews. so its weight will be on the concrete blocks, not the case. All this gymnastics is done for isolating the vibration of the AC unit from the computer.

The next point to consider is the copper pipes that are connecting the indoor unit to the outdoor unit. because space between the bottom of the heavy unit to the floor is only two cm, then those pipes can tolerate 2 cm pushing and pulling. No need to connect and disconnect the pipes. There is colling liquid flowing in those pipes and connecting and disconnecting them is a complex AC process. You need to learn that from a qualified AC technician and write notes. because you will forget after months if you need to do it again. There are two taps and a certain step by step process that you need to follow to keep the liquid inside the system. otherwise, you lose the liquid that is expensive to replace.

b - air flow hose in front of the big fan of the AC unit.

c - the outdoor AC unit.

a - this green plastic bottle is used for collecting the condensation of the AC unit but it never has any drops. When the case door is closed then in less than an hour the whole air inside the case becomes dry.

b- Two power supplies are inside the case. One is for GPUs and the other for the rest of the computer components. I turn on and off each one from outside using the switchers of the power board. Sometimes the machine is not mining. So GPUs are off and only one power supply is on for the main computer.

a - the power switch, power LED, reset switch, the hard disk LED are connected to a long wire and connected to the outside3 wall of the case.

b - copper pipes carrying the cooling liquid between indoor and outdoor units of the AC machine

c- Optical drive is connected to the wallet computer with a long SATA wire and power wire. The same method is used for the Supercomputer as well. In the next photo, you see its optical drive is outside.

You need to manually cut and paste and extend the length of the SATA wire and the power wire that connects the external device to the mainboard and to the power supply. The case is large, ordinary wires are short. This is a time-consuming task to connect two SATA wires and make one long wire. You need a soldering iron.

a - air flow hose

b- hole for wires going to the case is filled. so, no airflow.

c- hole for SATA and power wire for external devices

d- the power switch, reset SW, power LED, HD LED

e- BluRay optical drive. Connected outside the case. It is not used all the time. Sometimes I remove it and connect another SATA hard disk. This hard disk is used for scratch disk for video editing.

At the bottom of the photo, you see two power meters. One for the computer and one for the AC Machine. I keep track of the usage of electricity on paper. After I write it on the paper, once a day, I reset the meters. And once a month calculate how much electricity was used by the machine.

I opened the power board and cut the left side sockets from the right side sockets. do, this power plug has six sockets. the three on the left are connected to a long wire going to a power socket on the wall on the right side of the room. Three power sockets on the left of the power board are connected to another long wire going to the wall power on the left of the room. I did this to reduce the pressure on one wall electricity socket. This thing is eating a lot of electricity and uses a lot of ampers. so, I push it on two different wall sockets. One power meter measures the AC electricity and the other power meter measures the usage of the computer. I keep track of the electricity usage to decide about the profitability of mining. For some months mining was not profitable. It was using more electricity than its coin generation. These days prices of coins are increased and mining is profitable again. This machine is making between 20 to 30 NZ$ a day. So far it has covered its production cost.

Production cost (these are NZ Dollar)

_________________

5000$ - 5 GPU

1000$ - power supplies, CPU, mainboard, hard disks

1000$ - AC machine

1000$ - wood, metal, screws, work for making the case

$8000 - total

It has made more than 8000$ (after electricity) so far. (0.15 BTC plus some other coins)

At this time (Feb 2021, BTC is 64000NZD. so, this poor guy has made (0.15 X 64000 = 9600$) so far. plus a lot of other coins that I do not bother to calculate their value. It is good enough to know it made its own production cost. This is not a money-making machine that you can live on it. it is a fun project. Those rich thieves bastards capitalists that have huge mining farms with thousands of GPUs and with those fat ASIC machines are making money. We are just playing and having fun.

a- SUSE 15.2 Unix server for the brain of our robot

b- Wallet - this machine is back up for the wallet. The wallet program is running on the mining machine. Another copy is running on this computer. (not at the same time) when one of them is synched and downloaded the updated blockchain, I turn it off and turn on the other machine. Simple backup system. So I have the wallet on two machines.

c- a DOS box. This computer has only FDOS. This one is running a communication software with The Unified Field. I wrote the first version of this software was JavaSript. The second version is QB running under FDOS. This is the most important software ever written in any language in the last 60 years. I do not describe it here. I have explained the communication with the Unified Field in a few videos on the other website. Vegan-Religion.org. Mining is for 1X geeks. That software is for 3X geeks.

Note

____________

Each one of those GPUs can support several monitors. But I do not use them at all. Two monitors are connected to the internal graphics chip of the mainboard. I let the GPUs do their processing tasks, not being distracted with graphics for monitors.

These are alive people. I keep them cool, without stress, and they are glad they live in our office as free people, not as slaves of capitalists being squeezed for every cent they can drop.

AC is set to 16 degrees, but inside the Case goes down to a 10-degree centigrade

a- I reduce 120 megahertz from the speed of the GPU. So, when the Phoenix miner software is running, it can not push the overall clock to more than 1797 MHz.

b- at the screenshot point GPUs were at 1785 MHz which is ok. A happy computer is a cool computer that is not under pressure and stress. A happy computer makes you happy.

c- I increased the memory clock by 22 MHz.

d- I reduce 11 degrees for the target temperature of the GPUs. If it reaches that point it starts screaming and kicking and biting. But it never reached that point. GPUs of this happy computer never go above 55 degrees and at the screenshot time they were 39.

This is the default software of Gigabyte that came with the GPUs. it works ok. no need for other software. You can also modify the curve of the temperature control for fans.

You can write a bat file to use different pools with different mining software with different algorithms for different coins and assign each GPU to do one of them. This can be used to compare the results in real-time. Run them for a few hours and check the results. That was my early mining times. These days I just check whattomine.com and choose one coin and let all of them mine one coin. Then if I use nicehash, it converts them to BTC and I keep BTC. If I use some other pool I convert them to VEIL and keep VEIL. This is a reliable privacy coin with a reliable team. and you need VEIL soon, considering the mess that is being pushed on the planet. Bet on it. What was that comment? This is a geeky website. It is not the right place for political and economic comments. just a note. ask and you shall receive.

GPUTEMP is showing the GPU temperatures going between 38 to 48 degrees centigrade. Good software. works well. And it is free. I must send him some donations. His program works well.
