(Touching wood)
I use IBM deskstar (120gb) Maxtor(60gb x2) Fujitsu (60gb) and a trusty old Quantum Viking scsi 2 f & W(4gb as a "Scratch drive")
All are giving good service in an NLE environment, cramped in my EZ tower (With extra bays welded in) alonside my A1200 with hardly ANY cooling fans...
Just one fan at the bottom.
