And this means you'll be playing games? Which ones?
But most desktop computers are a lot of open space and that's not necessarily a bad thing. Because the more open it is on the inside the better the airflow will be, meaning it'll run cooler. I can't talk about that though because I have a mammoth case and am too lazy to organize the wires, so it's like a bird nest inside. It's a pain to hide wires from seven case fans, but the sad thing is that those seven run quieter than the fan (of the same size) that is on the heatsink.
