Still can't be bothered with mining though, because constant fan noise is a little irritating and not worth earning a handful of bitcents.
Meet my fanless miner:
http://iki.fi/teknohog/hardware/nanite/I plan to add another fanless GPU to this system. For example a HD5750 has about double my current hash rate, so it would triple the overall rate. This needs some power supply upgrades as well, but that can also remain fanless.
Actually, this is not strictly fanless. I have added a large and slow fan to be on the safe side. I cannot normally hear it under the slight noise of laptop hard drives.
