MOBO: This is what i'm stumped on i can't find a decent MOBO that's around $50 that has integrated graphics LGA 1155 and DDR 3.
Case: NZXT Technologies Source 210 Computer Case (Black) i'm not concerned with look as this is gonna be beneath my desk and always on
PSU: Cooler Master eXtreme Power Plus 500w Power Supply (RS500-PCARD3-US) $35
Notes: I don't need a GPU or sound card as this is mainly just gonna have DOS prompts up for running Minecraft servers. Also i'm gonna use the stock fan as i won't overclock with this. I have an optical drive laying around from one of my old prebuilts and i have VISTA lying around in some hole
