re: CDROM Drive.
The IDE Controller on WSP's is a decent controller, and will handle ATAPI cdrom's. As far as power goes.. the 45W supply won't handle a CDROM drive, hard drive, and the MB at the same time running full tilt (ie: during an install of an OS). My advice? for the install, use a separate AT(x) power supply for the HD and CDROM. ONce the cdrom is no longer necessary, power the drive off the internal power.
