mechBgon,
Built a system in an EnLite 7150 case using an MSI MS-6340 with a 600 mhz Duron for my wife. I've had pretty good luck with it for several months, so I thought I'd do another for her sister (now running a Shuttle board with a 90 mhz Pentium - my first Pentium processor ($700 at the time)). Not having any luck finding that case in stock, I went for the InWin, and would go for another MSI bd. - now the MS-6340M V5.0 with a Duron 800? After your last question, I might do a bit more research on size. Thanks again!
