Well my server has been acting up for awhile, won't fold smp and I sold the GTS450 so it's not GPU folding either. Probably a corrupted codec package or add-on (it's primarily a media server) so it's time to reinstall. I purchased a cheap C2D for a spare S775 mobo I had laying around so I'll switch it over there with the new WHS 2011. Now what to do with the Q6600 : 1) should I do a Windows install and run smp as a service? Could also GPU fold in the future as mobo has 2 PCIE x16 slots. 2) should I try musky's Ubuntu guide with 10.10 and smp ? I'm downloading the iso now but I haven't tried any Linux distros since Knoppix several years ago. Is it possible to GPU fold on Ubuntu? I'm considering slapping a wireless NIC in it and throwing it in the closet under the staircase as a dedicated folding boxen. (less heat in the mancave and no WAF hassles).
