I agree, ditch that mobo & CPU, and get something new. I’d see if you can find a MATX socket 939/nforce 3 mobo, and put that in there. If not, get a nice NORTHWOOD (avoid prescHOT chips, they SUCK), and 865/875 mobo. Gigabyte has some that would work in that case available from newegg & ZipZoomFly. Finding a decent northwood is a PITA though, NOBOY wants to get rid of them. I was just looking @ zipzoomfly & newegg, and EVERYTHING I see that’s micro ATX is all socket 754 with a VIA chipset. That’s not all bad, AMD/VIA combinations work pretty good, though I’d much rather have an nvidia chipset. I HATE the fact that you’re so limited when it comes to MATX mobos, there’s no reason they couldn’t make an Nforce 3 mobo that takes a socket 939 chip, that will go in that case!!! One thing is for sure, your current powersupply might NOT be up to the task of powering the new mobo/CPU combo. If the case won’t take a standard PSU, there’s almost no way to make it work. If it’s not a standard powersupply, you might as well leave that machine alone, and start from scratch. Build yourself a nice nforce 4 setup with PCI express, and a 939 chip. Any way you decide to go, you’ll at least be running DDR, and that will make a HUGE difference in performance! PC133 just doesn’t have the bandwidth to work well with a fast CPU anyways.
Now chaintech makes a VIA KT890 chipset MATX mobo. It’s the ONLY Micro ATX solution I see that takes PCI express graphics cards. I dunno, it would be OK to upgrade to that, and the mobo is only $65. Then you’d be able to run one of the new graphics cards that are coming out, and that system wouldn’t be totally out of date. I’d ONLY do that if you can use a standard powersupply though, because if you don’t, you’ll be forced to get a graphics card based on power requirements. That pretty much means low end CRAP only. If that’s the case, you might as well get a VIA KM800 chipset board from DFI with onbaord everything. That MIGHT not draw enough power to make the powersupply puke, but it’s still a RISK. Pretty much if that powersupply can’t be upgraded, I’d leave that machine alone. If you insist on it though, DFI makes a nice MATX socket 754 board with onboard everything. It’s $69, and it’s the best bet for that case. It would make for an EXTREMELY CHEAP upgrade, all you’d need is that mobo, 1gb of corsair value select cas 2.5 ram for $85, and a 3000+ venice core chip for $146 (retail with heatsink). Slap that stuff in that case, and it’s ready to go. I dunno what you have for a graphics card right now, but odds are it would work in that mobo if you wanted to keep it. I would suggest going to an SATA hard drive though, just to give a little extra. So, for just under $350 you get an A64 3000+ system with a gig of ram. That’s PRETTY GOOD!!!
The other route with the PCI express baord would be pretty cheap too, but add another $80 for a cheapo graphics card. Unless you bought a bigger PSU to run a nice graphics card, then it’s up to you. I dunno, good luck, whatever you decide to do.
