Plextor does not make any IDE CDROM's.
How about this one?

That's a writer, not a cd-rom. the original poster was correct : plextor does not make any IDE cd-ROM's

Why don't you get the ultraplex 40Max with a cheap adaptec SCSI card? (like the AHA-2904CD) The Adaptec card will cost you no more than $60 and it's specifically made for connecting CDroms and/or writers. And there's still no drive out there that can beat that Plex!
