You people suck at reading, he merely said that he currently has a 5GPU rig and has a $5k budget to EXPAND.

I put in 3 new circuits and built a nice big rack. some people using the metal home depot type racks. I built a wood one around box fans to blow over everything. Right now I'm about to start buying some better motherboards and going with 4-5 GPU's a rig instead of the current that is mostly 2 GPU's a rig. The current ones I bought super cheap and just started tossing them up but now that I'm approaching space limitations I'm expanding. I might just move the current motherboards over to a different area though.
