Budget: ~$400 (Under is good, a little over is OK.) Main uses of intended build: Storage/Streaming Media/App/Game Host. The latter is fairly undemanding, but needs a decent processor (Atom won't cut it). I've been using a rather ancient P4 box, which runs pretty hot (and therefore loud) even when close to idle; this will be on 24/7, so I've been eyeing Sandy Bridge for a combination of impressive performance and efficiency, but that's probably pushing the budget. Parts I have already: PSU (Antec EA-380D) HSF (Freezer 7 Pro) HDDs (WD 1TB+2x2TB) Graphics Cards (several, though ideally I won't need to use one) Parts required: CPU Motherboard RAM Case Case Fans (if necessary, preferably quiet) Ideally, budget allowing, a small SSD No overclocking, no real motherboard requirements. Case needs to have space for at least 5 HDDs (three currently, two for future expansion) and one optical drive, quieter is better. RAID isn't really necessary. Edit: OK, here's a possible combination that looks like it may suit. Gigabyte GA-G41M - $60 Intel E5500 (Dual Core Pentium 2.8GHz) - $70 4GB Patriot DDR3 1333 - $40 That's a total of $170. What I'm really having a hard time finding is a case. In the cart with those right now is the Antec 300 for $60, which would work, but I dunno. Ideally, out there somewhere is a small, quiet, understated (i.e. no blazing LED fans) case with decent cable management options. Also, in that budget there'd be room for a small SSD--a 32GB, perhaps? Recommendations?
