Well heres a 4th for the Q500, for the price its a very nice case, though i've yet to do anything with it until i get my mobo thats probably waiting in customs. The only thing so far that i personally dislike is the top mounted floppy. But maybe thats just me and who uses floppy's anymore? Though ive not yet put anything in her ive begun sanding her (by hand) for a custom paint job. (one solid color nothing special) good case for the $$$, i got mine shipped w/o PS as i will purchase an enermax 330 at a later date. Very solid aswell even with both side's and top off. The metal is thick too which is gonna be a pain with a nibbler.
Im with Silent Bob, except for a possible Lanparty rig (the Q500 is a heavy sucker) all my future comps will be housed in a Q500.
