This setup good for 5-boxing?

I also found this coolermaster case and it had a combo with a 1k watt powersupply, guess I should take that out then >.<

I just noticed that you said this above. 1000W is ludicrous for this computer. This system will draw a max of about 300 watts, maybe 350, at the wall socket when it's running full tilt. If I were building this for myself I'd buy a Seasonic 550 watt power supply.

The problem with buying a much bigger power supply than you need is that it runs inefficiently because you're drawing less power than it was designed to deliver. Power supplies reach their peak efficiencies only when they are delivering a certain number of watts, and 300 watts isn't nearly enough for the monster you've picked out.
