Here is my homemade rig. Did a wood prototype first, used it and then made changes and made aluminum one you see here

Total cost $28

Fun Factor: 9/10 (working with aluminum is fun and easy)

Used a non-ferrous blade in a powered miter (chop saw). Cuts the aluminum perfectly as if it wasn't there.

by the way, the 7950 cards are for sale here https://bitcointalk.org/index.php?topic=294747.0




This design works really good for gpu mining.
