I'm building a Litecoin mining rig with 5/6 7950 GPUs for fun and to get involved with mining. I do not expect to make much from this. Most of the stuff was paid for with Amazon gift certificates. About $300 of it is out of pocket. I've ordered and received most of the parts including the motherboard, PSU, 4 GPUs, 4 GPU risers (2 1x and 2 16x), CPU, RAM, HD, large tech tray case, and the OS. I have 4 120mm 75 CFM fans and a Kill A Watt surge protector on order that should arrive tomorrow or Saturday. I'm going to be building most of it today and taking pics which I will update my threads with later tonight. I'm also planning to do something interesting with an arduino board and LEDs. More to come about that. Here is a link to my original thread: http://www.exploitn.com/threads/ltc-mining-rig-build.17648/.
