reason for matx = i got a hp pavilion case with a window. beleive me, if i had a decent atx, i would get an atx mobo, but my only atx case sucks...badly. if i could get my hands on some spray paint, some plexi, my dads dremil, and some cathode tubes, i would mod that case, but it sucks for expansion, only 2 120mm fans, 2 hdd's 2 cd's and a floppy. and on top of that, only the psu that came with the case fits it unless i somehow cut a hole big enough in the back for it to fit.
and yea, i know to not go cheap, but in this case it isnt an option. but for now, i could get a decent mobo, and psu, but i would have to get a 128mb or 256mb stick of ram to drag me along until i got some money for a gig or 2. same deal with the cpu, just get something to get it running, and when i get the money, upgrade. graphics aernt a problem, i got that covered already, same with hard drive.
i have been looking into some am2 boards, but all the good ones are a little out of my price range. and seriously the biostar tforces are the best for overclocking on the matx platform? well in that case, ill do some research on those boards.
