Personally, I think the case is kinda ugly (the front). My friend bought a case based on the exact same frame, but with an actual aluminum front (flat). It's not a very good case for cooling (only spot for a 60mm fan in back and that gimpy duct which would need the holes drilled out a lot to gain any real performance).
My advice is not to buy a case just because it's aluminum. There are much better steal cases for the price. Take a look at
this case if you're really set on aluminum...it's about the same price, although no PSU. The PSU that comes with the above case probably isn't very good anyways...
