Holy Shit! It's posts like this that make me sad that GPU mining will eventually disappear.
I also like very much of these homemade rigs, specially the ones that do have a proper construction and not just plenty of zipties and hotmelt-glue.
Luckily GPUs will stay on mining on the scrypt side after ASICs dominate sha256 side, it will be interesting to see if BTC/TRC/PPC value increases even more and thus allows GPUs to stay longer on that side too.
