Not bad :O It could use a little cleanup in the bottom though. Remember, this is constructive criticism, so please don't take it like I think I'm the CM master.
If you are looking to make it look a little better on the bottom use 90* angles with the wires it looks a lot cleaner. You could also get a wire wrap and make it look as if 1 wire is coming out of the PSU and into the cable management hole.
Possibly, although I don't know what it exactly looks like. You should definitely do the hard drive reverse mount. Did it to my 900 when I had it and it looks so much better.
