The Dragon Lords doesn't have 5 drive bays?
Just checked and they have 4 native 3.5 inch bays and 5 5.25 inch bays, which is more than you'd ever need, so you could convert one to a 3.5 inch bay.
There's the Antec 300 which has 6 3.5 inch bays, but cable management's not the best (i.e. can't tuck cables behind the mobo) - the Black Illusion version looks v.nice though.
Cooler Master CM-690 II Advanced Dominator has 7, plus a built-in SATA drive dock - plenty of space in this case.
Xigmatek Midguard has 5
Everything else is getting expensive.
