I am using an antec 300. There are much better ones out now, but 5 years ago, it was a great layout with cable management and great functional airflow. I got 5 fans on it. 3x 12cm intake and the included exhaust fans.
I'm running a Define XL, as well. Fantastic case, just sadly compartmentalized, an problem fixed with the R2.
Mind posting some pics? I love seeing a Case Labs in the wild; I'll be ordering my M8 in a month, or two, for my upcoming loop.

Bitfenix Prodigy
The Sharkoon Vaya Value, basicly it was the cheapest USB3.0+sidewindow case at the time.
Node 304, it's so sexy I wish I could... never mind. Here's a crappy pick,notice how the desk lamp totally dwarfs it.
I'm using a MSI TC 128 case.
Pros:
Stylish,
isn't too big
Cons:
No cable management
No intake fans
my 212 Evo scratches on my side panel, i have to use some tape.
Absolutely zero workspace
I'm using a stock case from hp. Not sure what kind, rather modern.
Pros: Nothing
Cons: Everything about this case sucks. I hate it so much i wish I could throw it off a cliff. You don't understand...
Corsair 350D with full side window.
Cosmos II
Gonna throw out some little-seen love for my Zalman Z9 plus. It could do for some gromits for cable management, and it can get kind of dusty (the side panel has grating rather than a window, so it needs regular cleaning), but its got great airflow. Just wish it had front panel USB 3. :-(
Coolermaster Storm Scout II Advanced
3 pre-installed case fans (two LED fans at the front, 1 exhaust fan) plenty of room even for a Hyper 212 EVO (which is one of the larger CPU coolers available)
