I just remembered that I have a Dell Dimension 4100 somewhere in storage. It's quite a nice box, easy to work on, great performance in Win98 and Win2000. The last time I checked it had:
- an 866MHz Pentium III Coppermine (or maybe a 933MHz, I don't exactly remember if I upgraded it or not)
- 256MB PC133 SDRAM
- 64MB Radeon 9000 AGP
- original Dell mobo w/ Intel i815e chipset
- original Dell power supply (I believe 200w)
- Soundblaster PCI128
- 20GB Western Digital hard drive
- some random 3Com ethernet card (not that this really matters)
All in all, nothing too fancy, just a typical early 2000s system. It lacks ISA, though I remember having audio on Warcraft II when I ran it on Win98. I don't remember what the DOS VESA support was like on the video card, but I suspect it's not all that great. I'm tempted to install a Voodoo 3, but then that would reduce performance in a lot of Windows games. If I want 3DFX support, I'd much rather throw in a pair of Voodoo IIs. As well, I'd really like to throw in a Tualatin, though the board doesn't officially support them, and I'm not quite comfortable with pinmodding one myself (though I may still give it a shot).
