Heh, sorry, I guess I should have mentioned. I'm not gonna build a cab this time around, I'm using this kiosk/stand I found:
I'd like the computer to look "clean" since it's gonna go outside. Also, I already have the case leftover from another project, and just would like to take advantage of it.
Now that I've thought about it some more, I just need help figuring out what kind of processing power is needed to play the games I mentioned, not a specific motherboard recommendation.
Thanks for replying.
