HP 9200i internal SCSI CDRW
Adaptec 2930 SCSI card (for SCSI drive)
Toshiba DVD drive
Western Digital 80GB 7200RPM Special Edition drive for the OS/programs
Western Digital 100GB 7200RPM normal drive
floppy drive
breakout box with card reader and 2 USB ports that came with the mobo

That's everything! Not much at all. I don't even have a sound card because I'm using onboard audio. and my situation wasn't much improved when I didn't have the SCSI card or SCSI burner installed.
