To quote the specs of your case:

Radiator Mount Locations
Front: 360mm
Top: 240mm
Rear: 120mm

As such, you can use any AIO that fits within these restrictions. It just depends where you want to mount your radiator, where you want the hot air to go, and how good cooling you want. From the looks of the case, I'd go for either a 120mm rad at the rear (exhaust) or a 240/280mm rad at the front (intake) - it looks like motherboard/RAM clearance for top radiators would be tight. After you've decided (or nearly decided) on the size and placement, read some reviews to find what fits your budget and desired cooling potential.
