Way to go QCK!
Maybe you could report back in the 630 owner's thread after a while and let us know if it helped at all with some of the problems you reported with your 630 that has been upgraded... I assume you didn't upgrade all 4? You may be a perfect test case... I know that upgrading the HD on my 530 (along with a fan) completely stabilized my 530. Maybe there is hope here as well!
