Those dualminers are pretty cool little things. I've been tempted to get a few since my old gaming rig (now mining rig) isn't exactly stable sitting in my garage, especially as temperatures heat up. Too bad they're *WAY* overpriced due to being a dual purpose chip.
Yeah, they get only a little tiny bit less expensive buying in bulk too...The asicminer U2s are out. 15BTC for a box of 500... .03 BTC each, plus some profit, plus shipping...
