ok, call me an idiot, but i've finally decided to upgrade my aging PII-400 rig. i plan to do it piece by piece, starting with MB/CPU/RAM. this is offtopic, but i figured people here would know the answer since there have been posts talking about OCing the 1600 on this thread. i plan to order the 1600+ from Newegg, pick up a MSI KT3 Ultra-ARU DDR from fry's, if they're still available, an AX-7 from SVC, and maybe a stick or two of samsung DDR (probably pc2700). my main problem is that i want to use my old case for now as i can't afford the new case i want. the old case is an antec midtower that has an antec 250w ps... it has minimal space, not much cooling. it does have a prebuild rack for a front fan, but looking at the slots built-in, it may not do much to cool. i want to OC this 1600 up to 1.7-1.8Ghz eventually, but at least run the 1600+ at regular speed and locked, stable. will this case/ps handle it? or will i have to wait for my new case? thanks.
edit: in case it matters what components are inside (i have no AGP, btw), i have 192MB SDRAM (PC100, i believe), two ethernet cards, a graphic card (riva tnt 16mb), a sound card (SBLive! Value), a dial up modem (unused), a 10GB hard drive, 40GB hard drive, a DVD-ROM drive, and a external CD burner. so yes, i'm pushing the ps hard enough already. you think it can handle a new mobo, ddr333 and 1600+?
