They don't have to gather air into themselves so their flow rate is increased. A grill with no fans will just add to the resistance the rad fans have to work against.
If the water temps are kept relatively low the air temp in the case will be lower too. Its a much better airflow system than most cases.

The build log for my case will run you through the case, it's layout and how it'll work and you can ask questions about it there if you want.
Mine has two 360x60mm radiators as intakes on the sides with a single set of fans in push. The air that is being pushed into the case even under load is cool, so don't stress about it heating things up. Nothing in my loop heats up very much at all. The top of the case has two fans which exhaust the air out of the bottom section and also actively cool the backside of the motherboard.
It's similar to my last build which I cut a hole for a single 140mm fan in the top to do the same thing.Image (Click to show)
Thanks for the great advice guys. One last question. I was thinking about doing a plexiglass "Lid" that would sit ontop of the platform and screw it down on the edges with thumb screwes like you would a normal case panel.
The question I have is. Will the closed section of the plexiglass capture heat? Would I need to have some kind of port?
I was also thinking of doing a stainless steel Mesh as the cover. So it could also be free-flow air but restrict dust.
I do not think that there will much sound to dampen, as the top section will be insulted by the 1/2" thick material (12mm)(which I still havent decided which to use, I was going to use a stained Jarrah, Brushbox, or something, I really like the look of high quality stained timber)Edited by Noviets - 9/28/13 at 7:23am
