Well, for small factors, Intel has a better platform anyway. I haven't seen any mATX boards with AMD's latest series of chipsets (though I think ASRock as an ITX board); they all seem to be re-branded AM3 boards.
There are better GPU's for the money, such as the Radeon 7950, but it sounds like you're pretty attached to that card in particular. However, without a side-panel window, I really wouldn't put any emphasis in aesthetics.
I did look into m-ATX cases with side-panel windows, but came up dry. I also tried looking for a less expensive case that didn't feel outright cheap, but also came up dry. I did find the Silverstone Temjin TJ08-E. I like the styling better, and it comes with a single front-intake 180mm Air Penetrator fan, which creates positive air pressure, and directed right at the CPU. I'd mount the cooler's fan in a pull config for maximum performance. Also has a removable motherboard tray, which should make building it a lot easier.
I'd also spring for the CM Hyper 612. Solid copper base plate with 6 heatpipes. It's a lot more heatsink in the same price range. I have the original Dark Knight, with the same 3x 8mm HDT heatpipes; about the only difference is mine is nickel plated copper instead of a ceramic coating, and if anything, I would think ceramic coating would degrade performance. Honestly, I'm a bit disappointed with it, though it's not bad either as I have a 4.5GHz OC with my 2500k, but it gets up to 68c (~42c over ambient). I didn't live up to the price I paid for it ($50). As I've said, without a side-panel window, internal aesthetics don't mean much, so I'd spring for a beefier, albeit, less attractive cooler.
Last bit of advice is the SSD. I'd go Plextor M5S, which is basically a Crucial M4 with 256MB of DDR cache added on. It features 8 more GB's of space, blazing fast (71,000 IOPS random read vs 23,000 of the SanDisk), and delivers consistent performance since it doesn't rely on compression like SandForce SSD's, thanks to the Marvell Controller. At the same price $115, there really isn't any reason not to get it.
