Here is my latest mining rig I put together.
Recently I ordered a CPU for a motherboard I had purchased and they sent me the wrong one so I ordered another motherboard to fit the CPU they sent me and stuck it in a wooden crate I had found at a jobsite I was on.
Pretty cool huh? Personally I think computer cases are over-rated. I have easy access, it runs super cool and with the two cheap ass video cards and the CPU I added approximately 350 more hashes/second mining cryptonight algorithm. Not bad for less than $200 bucks.
