I just snagged a free DELL Optiplex Gs the other day (P166) and it works fine. The funny thing about it is most people used a small heatsink and fan to cool a Pentium 166 while dell has a huge towering copper heatsink that looks like a tree and then a shround that directs air over it from the PS fan.

Thw Gs also has built in S3 video which is OK (1MB up to 2MB VRAM). The Matrox Millenium card is great for Win95 once you go to Matrox and get the proper drivers (not included into the Win95 cd). You can also go find cheap 3DFX cards on ebay if you want to play some of the original 3D games.
