Best cases for the money are still steel, especially the new Antec SX’s. Money no object there’s no question it’s still steel also: the Supermicro cases.
That aside, going with Al cases, the Antec PerformanceOne P160 is a good one. It’s not a full tower (at least by my definition, but then again I consider a full tower nto just barely fit under a desk, usually something about 36″ tall), but it does have an optional side window, uses 120mm fans, has a pre-stealted drive stick-ons for two optical and one floppy drive, has 4 5.25″ bays, 2 3.5″ bays and 5 disk drive bays and a removable motherboard tray. No wheels or castors though.
