So the max rad size the case can support is a 240mm, which is enough for a CPU only loop.
Then I advise this kit.

Not the best radiator (would have picked the EX series, but for some reason that adds on more than $100) but it will be fine.
It will come with everything you need for a CPU only loop, except for Coolant [strike](ignore the free Deadwater, you dont want any pre-mixed coolant)[/strike] and some anti-microbial solution.
For the Coolant. Plain Distiled water is recommended and can be found at most supermarkets, is also available from FrozenCPU.
For Anti-Microbial solutions, you have a two options to choose from.
1. A Biocide, its a chemical that kills any bacteria or Algae that may grow in the loop.

EDIT: Just realized that the Deadwater is actually Biocide, not a coolant.
2. A Kill-Coil, basically a small strip of silver that also kills bacteria/algae. Drop it into the reservoir and your good. This is what I use since you dont have to re-apply every time you open up the loop.

I also suggest you get some kind on drain valve or T-Line on the loop, makes emptying, maintaining and upgrading the loop later on a lot easier.
