My only current rig for HWC is what you can see in my system specs but I have two other units that I can bring on line if/when I feel like it. The first one is an i7-920 with two gtx 570's w/ 2.5gb each and 12gb. The second one is a quad-opteron with 64-cores and 64gb of DDR-1600. There are some others but they are doing things like video encoding and game serving so they will most likely never be deployed, and I don't fold on my laptops anymore
