I'm not big on fancy cases. I sunno, just too garish.
I would go with this case...

or this one with the window.

I really like the color. But on the downside, this is a big tower. I wish the smaller versions were just as inexpensive. It's just too big. But it's roomy enough that heat shouldn't be a big problem. Especially with an extra fan.
You jst need this 520 watt power supply to go alone with it. You can even get it in matching blue.

Or, if you wanna risk a tigerdirect rebate (I've heard they're unreliable but have never tried one myself) you can go with this baby. 500 watt power supply plus glossy balck case for $20 Ar.

(Another odd thing about this rebate is that the web page says you need to make a $300 purchase but the rebate fine print doesn't state anything of that nature. It just seems funny so I wouldn't trust it.)
My personal favorite case right now is a luxury item due to cost. It's just not worth $110. But the Overture is nice.

It's not too big or too small. It'll hold a full atx motherboard. (Though they say if you have a tall graphics card with a large heatsink it may not fit by a few cm's.) It's roomy enough for two external 5-1/2, two external 3-1/2, and three internal 3-1/2 drives. It's supposedly ultra quiet. And it's sleek and compact. Big enough for plenty of drives but small enough to sit on a media shelf. If money was no object I'd get this.
As for the indsides, for the past week I've been looking at the market. I've come to the conlcusion that this is the worst time in several years to build a new PC. It's too skewed to the high end or low end. And who knows how the transition from pci-e is going to pan out. In another year we'll have the first dual core processors. I think the graphics card market will be more signifigantly altered than usual in the coming year. It's just the absolutely wrong time.
I woukld go with a last generation pc if you must have a new pc and just wait another year or two. Like, a semperon 3100 and a simple agp system. It's cheap and effective and will do everythign you want it to do today. Especially if you overclock it.
