Hi Cubists, I replaced my stock WD 20 gig HD with a new 80 Seagate drive. Wow, I can't believe how quiet it is--it's eerie. When I was transferring data over from a Maxor 40 gig drive it sounded like a train wreck in comparison. Makes me wonder how I will be able to tolerate a CPU upgrade with a fan. Speaking of processor upgrades, the possibility of the sleep/coma problem with a Powerlogic upgrade is kind of a dealbreaker for me. I wish this would get resolved. Anyone know if this is also a problem with the Sonnet upgrades? T.
