I'm just about to buy a Shuttle SD31P but need a little helping choosing a few components.

My CPU is going to be Intel 630 P4 3Ghz 800FSB

I'm having trouble chosing the memory. I want 1Gb but not sure which one to buy. I have been looking at Corsair.

I also want a silent graphics card for general use which has a DVI output - it has to be as quiet as possible.

I can't decide which manufacture of SATA hard drive to get. I want silent and good performance.

Generally I want a good performing PC but not for games. Main use is multimedia, graphics, audio visual processing.

Any advice apprreciated.
