I loved my Q500 when I first got it. Heavy as could be, solid construction. My roommate had one already and it seemed great. Loved the removable motherboard tray. Then after awhile it kind of didn't work out. It seems hard to cool to me and my roommate. He's got fans in front and back, the thing is loud as can be, but it still runs hot, even with the side panels and the top completely off (putting them on is dangerously hot). I just got an Antec Plus860, and I'm pleased with it. Even with the stock fans in it, it's very quiet (meaning 4 fans total, 2 case fans, 2 PSU fans), and as cool or cooler than the Q500. The 860 is shorter too, but almost as heavy, and I prefer the front design and the side panels (I hated removing the panels on the Q500). Plus, removable drive bays galore on the Antec, though no removable motherboard tray, which turns out not to be much of an issue, plenty of room. With the Q500, you have to remove the motherboard tray just to get at the 3.5 inch drive bays. Also no front USB or firewire, which may or may not be an issue for you, but it's a nice feature. The Q500 is sort of a venerable old case now.
