Hi there to everyone, I am thinking of getting one of those Aopen shuttle cases or something similar from Ebuyer. Two problems; (1) I have an Atholon XP 2800 Cpu and want to keep it,will the motherboard allow it? (2) The sort of configuration I see is this; 512 DDR 3200 ram, 80gb hd, silaro F5200 agp graphics card, NEC 16x +- DVDRewriter. not so concerned with the sound, I have a creative labs LS Audigy or can live with the on-board sound option. The power supply of the Aopen is about 220w I believe, is that going to be enough to power all of this?
