Tonec - that's exactly what I'm looking for, thanks.
Bignate603 - that's an interesting idea -- but I don't have room for it in my case.
I think 300w should be plenty for the following devices:
asus p2b-ds, with 2 PIII/600
256MB RAM
4.5GB SCSI drive
30GB IDE drive
SCSI CD-ROM
SCSI CD-RW
Sound
Video
Network
Modem
I need the extra connector to connect a 15/30GB Quantum DLT drive.
