Been meaning to post this for a little while, but I've only just got round to it. 6 x 7950s with another 3 soon to come. Currently managing about 3600 kHash/s mining litecoin. Its a group project with six of us involved, but I've ended up doing most of the setting up seeing as everyone else had exams, whereas I'm on a year out from uni.
Nice woodwork.
Lol, thanks, I hope its not a fire hazard! Obviously the GPUs will cut off if they get too hot, and there's a circuit breaker in case of a power surge so hopefully its all good. Should be making some metal frames eventually though.
