Ok, I'm back home now.
I made a mistake, I'll list the parts i currently have:
MSI 915P Neo2
Kinston 1 gig (not sure of timings)
Intel Pentium 4 3.0 775 (Processor 630)
Xfx 6600GT pci-e 128mb
maxtor sata 80gigs
I want to get a case which comes with a power supply, but the place where i bought the parts recommended i get a 450 Truepower, but the cases I can get either have 400,430 or way too many watts. Are the cases witht eh 430Watts enough to run the computer?
