This looks like a great budget case for the Econobox and at $49.99 on Newegg
is really giving the Antec One Hundred a run for its money.
It has tons of features for a budget case, bottom mounted power supply with fan intake, USB 3.0, expandable to a total of 7 120/140mm fans, holes to route power supply cables behind the motherboard tray, and it can even mount a dual fan radiator on top. It doesn't look to ugly either. In fact I quite like the look of the white one with its painted white interior and has replaceable expansion slot covers, not cheap punch out ones like in the One Hundred. The only drawbacks with the case that I can think of are that you're limited to the lower hard drive bays if you have a long graphics card and there aren't any dust filters.
And if you don't want USB 3.0 there is a cheaper version for $10 less.
