I have a couple of old PCs gathering dust that might be cannibalised for such things as CD-ROM drives (I think one is a writer), case etc. Most of the working guts are unlikely to be of use due to age.
There are no monitors (you cannot stack monitors very effectively, necessary when trying to avoid their detection by irate wife!), but a few mice (PS2 & serial), and an odd wireless keybd / mouse combo (untested) and a new PS2 keybd, various power cables, etc.
Free to those who can pick them up.
If you wany anything specific, then feel free to ask, as I have many years of accumulated bits and bobs
