Looking for advice on a build for an inexpensive (ideally $200 or less) PC to run MAME cabinet that I'm building. I'll likely just be putting the components directly into the cabinet. I had looked over some of the Micro PC options (Kangaroo, RaspberryPi, NUC, etc), but it seems like doing a build with individual components would be a cheaper way to get much better specs than you can get from those machines. I'm hoping to emulate mostly older games (NES, SNES, Genesis, earlier MAME) but would like to at least get through N64 and some of the late 90s early 3D fighters on MAME (think Virtua Fighter-ish). I'll probably run this off of Linux with Hyperspin or MALA on the frontend.
I had looked at some components on sites like NewEgg and came across chips like the AMD A6-5400K, which (on paper) seems like it might be a nice option - clocks to 3.6GHz, has an integrated graphics card (which, from my understanding, is nice to have but not as critical as clock speed for most emulators and frontends), and is only $40 at the moment. Combining that with an entry level MicroITX motherboard and about 8GB ram with a ~120GB SSD seems like a reasonable package for this purpose and would come in around $150 or so, which would be great. I'm just wondering if I'm kidding myself to think that this processor would run the type of games that I'm looking to play without hiccups. If it is inadequate for what I'm looking for, any recommendations for "budget" processors that might work better?
Any advice would be much appreciated, especially from those of you who have built for this purpose before. I'm new to building computers but thought this would be a fun project to try it out...
