Aopen XC Cube Black EZ915?

Looking at building my first SFF.

Its a budget system, don't really need, or can justify dual core system, and would like to salvage as many parts from my current system.

Will using my current:

GF (Gefore 6800)
x2 SATA HD's
NEC DVDRW
5.1 Dolby Digital Live! Sound Card
CPU P4 3.0Ghz (775)

Will this all be OK?

From the spec at ebuyer, i don't foresee a problem, but ain't built one of these before:

ebuyer

product code: 90707

Will be doubling my RAM, going for 2GB (2x1GB) can anyone recommended which RAM will be the best?

Cheers, Sam
