im constructing a cab, but i was wondering about the computer monitor. i know the bigger the better (most cases), but for just running roms and thats it, does it matter which brand i get? theres a monitor on ebay i found thats a 21" mitsubishi monitor for like $80. its a little used, but thats all. will this run all the games i have? i have old atari games, to metal slug type graphics. i just want enough to run the stuff without looking like crap. and also, whats a video card that is "enough" to run all the games. thanks in advance for any help!
