Need help finding a monitor arm with a large clamps

I have a ikea desk, and I want to am looking to get a monitor arm to clear up some more desk space. I know the clearance on clamps for monitor arms are not generous, so is there a monitor that has a large gap within the clamping space?

this is my desk for referance; http://www.ikea.com/us/en/catalog/products/40244850/#/20244851

Most of them are going to come with 3-4 inches of clearance no problem, but if you wanted a cheap solution

I'd like to ask, since I may need one soon enough, is Arctic Cooling monitor arms decent or should I look elsewhere? Basically, the Arctics are the first arm that I found in my country... That's why I'm asking...
