The Newegg case configurator can give you a selection to choose from. But the 3000-B is excellent for the money - the Compucase 6A19 is the same but without a door (directron.com is about the only place that carries it routinely - it may be listed under HEC now). Almost any case with at least 4 (assuming you'll want at least one optical drive) 5" bays will get you there - you can use something like the CoolerMaster HD rack (4-in3) to put 4 HDs into three 5" bays, or the Lian Li version which is similar but has a prettier face - the CM is technically a better solution.
. Newegg has over 250 cases that have 5xHD bays another 80+ with 6 bays. Plus you can always add more with the racks I mentioned (there are 4 in 3, 3-in-3, 3-in 2 models available) - or even with individual 3.5 to 5" adapters.
Here's a
Link to the one G-Y mentioned. It is identical inside to the Silverstone version I reviewed here:
http://www.techimo.com/reviews/ . I currently have the 4-in-3 rack in the bottom 3 bays of my Silverstone (which is hard to find any more).
And here is one I like because it looks all-business...
Codegen 9000 series. You can get it at Dealsonic.com w/o the PSU.
Here is another excellent case that holds six HDs to start if you're willing to go the higher cost (several other brands, Tt for one, sell cases made on the same base chassis):
Enermax CS-10182 .
Aerocool makes several cases with lots of drive room.
My CoolerMaster
4-in-3 rack is for sale - PM me if interested. Quite a few places are OOS on it.
