That is the basic layout, the base is about 3/4" thick with the inside of the block being 1/2" deep
The top is whatever material is available (preferrably clear, but doesnt really matter
The holes on the corners would line up with AMD mounting holes
Those black squares are little copper squares that are the full height of the block to get some serious turbulance in the block (could use any shape, I don't really care, whatever is easiest for you to make)
Any other questions, email me
