I have a fairly old SBLive!, an Adaptec 19160, two Atlas 10KII's, an Ultrastar 18LZX, a Lite-On 24X CD-RW and a a WinTV-Go capture card all still in my machine.
I did have two original 1994-1995 Matrox Millennium cards running extra monitors until I found a nice dual-head PCI GeForce4 MX 440 to run my side LCD panels.
I guess my Pioneer 2X DVD burner is getting pretty old, too.
