In need of a new case, specifically one that can fit a cooler master seidon 240m

[CustodianofDogs]

For reference here is my current build:

Case: Cooler Master HAF 912
Power Supply: Corsair RM1000
Graphics: Gigabyte GV-N970G1 GTX 970
Motherboard: ASUS M5A99FX EVO R2.0
CPU: AMD FX 9590 Vishera 8-core (this is the problem component that requires said cooler)
Storage: WD Caviar Black 1TB
Memory: x2 Crucial 4GB DDR3
CPU Cooler: Cooler Master Hyper D92

This is my second build, which I put together this past January. I didn't have a problem with cooling over the winter months, but now as the summer approaches, my computer is crashing from overheating quite frequently. I've been looking to get a Cooler Master Seidon 240m and I need a case that will have enough room to fit the cooler and all of my components.

There are tons of cases that will fit a 240mm AIO. What else do you look for in a case ?

Well, size isn't really an issue as far as being too large. I'd like something that has plenty of room, keeps dust out relatively well, looks good and is preferably under $200 or so.
Also, on a semi-related note, I don't have any experience with water cooling components. Do you have any advice on maintenance or testing the cooler before I put it in my case? I am kind of anxious about the thing leaking on my setup.
