Computing moved very fast back then so it can be a bit hard to pin down the exact era you want. But with that in mind personally I'd do it completely differenty. Get an Athlon, Athlon XP or Duron of 1.0GHz or faster. A DDR socket A board Geforce 2MX/ 4MX That was the basic plan for effective budget gaming back then. Add as much ram as you can (don't worry about speed, it'll probably run at 266 anyway), get a PCI SATA card and a cheap/ old SSD, use a new psu (just a cheap basic thing, these things ran on 230-300W units that came bundled with a case). If you want to target a slightly earlier era use an earlier Athlon/ Duron, SDRAM board and a TNT2. A PIII/ Celeron is ok too.
