Eh... That MSI is about 250 now... Hope you waited to buy...

4 GPU system
Power Supply $285.15 GPU 4x$377.36 $1,509.44 Total $1,794.59 Kh/s 2976 Kh/$ 1.658317498704439

The system has been mining with 3 GPUs for over a week now. The case brought down the temps so much that I now run the fans at 80% instead of 85% and increased the voltage from 1.100 to 1.125. Hash rate per card is up to 744 from 722.

Just got the 4th GPU today. Will try to get updated pictures after I get the 4th GPU installed. Changed the way the power supply is installed since it will only have one now.

I think I will be sticking to 4 GPU's per system since that should get me somewhere around 1000 watts (not sure yet as 1 was 300w, 2 was 500w and 3 took it to 800w). Trying to stay close to 80% of the PS's capacity so that is 960 watts out of 1200 watts.

Thinking about the cost of a 7 GPU system vs a 5 GPU system.

Everything else being equal:

7 GPU system
Power Supply 2x$285.15 $570.30 GPU 7x$377.36 $2,641.52 Dual-PSU ATX Adapter $10.00 Total $3,221.82 Kh/s 5208 Kh/$ 1.616477643071308

5 GPU system
Power Supply $285.15 GPU 5x$377.36 $1,886.80 Total $2,171.95 Kh/s 3720 Kh/$ 1.712746610189001

So it looks like I would get more Kh/$ using just one PS and 5 GPUs.

This assumes I can run 5 GPUs on just one 1200 watt PS which is yet to be seen. I suppose I could try a single 1600 watt PS for 7 GPUs but I really like the Corsair AX1200i because of it's monitoring features.

First GPU installed. Starting to rethink running 7 GPUs with two 1200 watt power supply's from a cost perspective.

Stop using branwallets

Any plans to make this hold two motherboards and double the GPU's in the future? It would get a little tight, but I think it would fit.

You are not special.

It looks really nice and clean. How many GPUs are you going to install?

Would you mind updating with total cost of the rig and case once you're done?!

Thanks.

Big update. Case is done!

Now I am in the process of mounting the components...

GPU section:

Power Supply section:

Had to figure out a place to put the SSD and other misc componets. Velcro came in handy here:

That's it for now. Will run it as is without GPUs to get a baseline of power usage. Hope to get the GPUs installed in the next few days as time permits :/

I live in a high rise so this is my version of a garage. Storage units for resident use. Well lit and free electricity but gets hot down there.

Thanks! Looks like a good place for building stuff. Good luck. I'll be interested to see how it goes.

How do you plan on attaching this case to the rack? Very interested in this as I have an old unused server room with many 4 post racks that I'm eyeballing for a similar build.

For this first one I will use my existing rack shelves. In the future I plan to use something like this:

Those are pretty cool actually. Gives you a bit more airflow around the underside of the motherboard aswell.

How are you planning fans to be mounted? Any updated pictures?

Here are the aluminum part used:

...and one more for the Power Supply section:

Worked on the motherboard section tonight. Screwing in the MB standoffs worked better than expected.

Really had a hard time drilling the holes since the top part of the frame interfered with the drill. In hindsight I should have turned it upside down and drilled from the bottom :/

Test for fit. MB screws not tightened down.

Finished MB section:

Where did you get the parts? It looks really nice!

I initially looked at using 80/20 for the case but found it to be too expensive. Consisting of 1" square extrusions I also think 80/20 takes up too much valuable space on the interior of the case. Trying to fit 7 GPUs in the width of 442mm is going to be hard enough without also loosing 2" for the side walls.

The way it is now I have 442mm of space for GPUs. 4mm for the aluminum sides (2mm each side) and then another 2mm for the side panels (if I decide to use them) for a total of 448mm. Looking at how it turned out I think I could of increased the interior to 444mm and put the sides on within the space between the long aluminum pieces.

This is a learning process for me so I'm finding what works along the way

I think these are the two size angle bars I am using:

http://www.homedepot.com/p/Crown-Bolt-1-2-in-x-96-in-Aluminum-Angle-Bar-with-1-20-in-Thick-56780/202183473#.UfNGEiTn-M8
http://www.homedepot.com/p/3-4-in-x-96-in-x-0-050-in-Aluminum-Thick-Angle-56930/100337439#.UfNGDCTn-M8

Larger pieces for the exterior frame. Smaller ones will be used for the interior GPU stand.
