I can see having a category for the Apple II or the like, but I really don't see a need in listing old IBM or Compaq computers in hardware. There's a shift in the mid-80's from stand alone, buy this computer and play games (Atari 400, TI 99/4a, Amiga) to what I would consider the grandfathers of modern computers (386, 486) in that the newer ones could be changed and upgraded. Even our IBM PS/2, which was running Windows 3.1, had several parts switched out throughout its life. I think when it gets to that point, the explosion of IBM-compatible computers is a lot more than this site really needs to be tracking, in my opinion.
