Probably a Pentium II 266 MHz w/ 64M in a full ATX case. CD-ROM and floppy. No hard drives, but I have some very small IDE drives if you really need one. Vaguely recall the memory is DIMM instead of SIMM, so it's probably topped out memory wise. Might even boot, but please don't count on it. Free to first taker. Keep some cadmium out of a river in China. Andy
