I'll be the first to come out and say I don't necessarily recommend that Antec case.
A few reasons why:
It doesn't have a lot of airflow coming from the front of the case. Like take the Cooler Master Centurion 5 for example, it has a front grill type of ventilation that means you can put in an intake fan which would give you an input and output flow.
It also looks like it'd be rather difficult to install a fan in the hard drive enclosure to begin with. The Power Supply, as others have noted, is merely a Seasonic stamped with Antec on it, but for over-clocking, not a very good 12V amp over all to support the higher voltages.
I wouldn't recommend using anything other than an E4300 + 7600GT + One SATA Hard drive + one optical drive + two sticks of ram on that particular PSU.
A nice case, definitely good enough for the average gamer and if you install a side mounted exhaust fan, it has potential to offer good cooling, but it won't support a front mounted intake fan without cutting the front panel, which will potentially make it ugly or obnoxious looking.
For $100 though, you could've definitely gotten a more gamer-friendly case like the Thermaltake Armor Jr. or maybe even an Antec P180.
