I know that this is a Mac-based forum, but as I've noticed that there are usually nice people that post I thought it might be safe to ask: are there many mac users that have gaming pc's? I was just wondering because I need to get my brother one who will only game on a pc (titles he said are easier to buy for pc's). And so... I just needed a little help on what to get or whether or not I should try and put one together myself; putting in an old optical and dvd drive and then adding the rest. Would this cost less or more in the end? Any ideas out there? Specs I should definitely consider? Please, all recommendations and comments are welcome.
