Here is the list of tools that I used.

1. Nipper

1. Zip ties

Screw drivers

Well, I just couldn’t wait for all the parts to arrive, so I started do some preparations.

Here are my steps that I took to build. Please let me know any suggestions.

*Make sure to plan ahead where you want to tuck away all the wires.

1. Making motherboard stand

1. I cut off some of “rail cover” which will be used as GPUs stand in small pieces of 4. Made a few holes on them with dremel and zip tied on the plastic crate. I made a little slit under the plastic crate so that zip ties can stay still in a place and also the plastic crate doesn’t rock.

Here is the finished image of motherboard stand.

This is how motherboard sits on top of the stand.

2. Plastic crate prep

1. Now, we need to cut away some part of crate so that DVI ports can be accessed. Place a GPU and mark where plastic will be cut off.

After cut away 3 parts and placed GPU with GPU stand for the fitment.

3. Motherboard placement

1. I made a hole on the side of crate for zip tie to fit. This will fix the motherboard.

4. PSU placement

1. For my build, I decided to place the PSU on the side of the crate.

5. GPU stand

1. Make 2 holes on each side of plastic stand and zip tie them.

6. GPU placement

1. Placed 1st GPU. Screwed it down with #4 3/8 metal screw.

1. Make sure the DVI-VGA adapter clears the cut.

7. Etc

After placing hard drive (for Windows), all you have left to do with the rig is to install software.

8. Complete!!!

Currently running 700+ KH/s on each card at ~70 C. Very stable! =]
