My Compaq CDTV 520 (added to my collection in 1998)
This PC quit POSTing, I have no clue what the issue is, it does not seem to run any code on power up from what I can tell with my diagnostic tools. Many parts have been stripped to use elsewhere until I can repair it.

Originally this PC shipped with an NTSC TV Tuner, however it has no driver support in later versions of Windows, and NTSC broadcast is dead, so I removed it in favor of a SCSI card.
