I'd really advise against the 900- if you're going to get a 900, get the 902 so you have some air filters and a couple of other improvements. Still, it's a solid case, but at times just a pain to work with and wire management is basically non-existent (I used it as my primary case for ~4 years; finally swapped to a Silverstone Raven RV02E in January). But if you're interested in something that is 900-style, I recommend getting the Silverstone PS05-

I put together a build for a friend with the PS05 and basically... after having had a 900 for so long, just sat through the whole build and was like, "Agh, really wish this was out when I bought my 900".
There is a window version, although it's tough to find. You will have to buy and install case fans, so don't take the 50% price as any indicator of quality or savings because you'll end up paying about the same for either when you're done (maybe less still for the PS05 depending on the fans you go for). Nonetheless, the fan installations are easy (two of them you literally just place them in a compartment and you're done, no screwing around; otherwise, the front intake is easy because the mount comes off nicely and you can screw the fan in with ease while the bottom intake mounts inside the case but you just turn the case upside-down and screw it in; very easy) and it lets you get better fans than the 900's Tricools.
And yeah, unless you go really wrong w/your fan selection, the PS05 is a lot quieter while sporting similar cooling performance and significantly better dust control, cable management, ease of installation, etc...
