I started with a single 5870 prototype back in 2011. Moved up to 4 x 5970 rigs (wish I had pics of them, but I dont) and it finally grew into me building a shipping container to use as a datacenter to host everything so my relationship would survive, lol... also didnt have the power or A/C in my house to host all the crap, lol.
Here is my farm I'm getting ready to say goodbye to...

GPU's were so much fun and so much of a pain sometimes lol. We really put ourselves into it. Goodbye GPU Farm! RIP
