You should be fine with it. You'll probably need either the DSATX or M2-ATX power supplies to power it, though. I would go for it if it did end up being a good amount cheaper.
ok i have a pentium 4 1.6ghz desktop and i was thinking I can use some of the parts from it to build my carpc but not sure how much power it would be to power it in the car . Would it be too much or should i buy a pentium m and new mobo, if i use the 1.6 ill have to buy a mini mobo that supports it but it would be cheaper . what do you guys think and what other parts could i use?
