How much is your shirt worth? I have recently been looking into building a mame pc and I have found that parts to build these days are quite great. But of course that all depends on how much if any money you got to spend and how much power you need. I am currently looking at about $60 for mini atx mobo, and $120 for Intel Core 2 Duo E7400 Wolfdale 2.8GHz, and $55 for 250GB hard drive, I already have memory and power supply. So for under $200 you could build a decent pc. I am sure this is more than I will need for most the games I will play but I want to use the pc for other things in between gaming. I have also decided to not use a case but build one to custom fit in my cabinet.
