Firstly this thread got me to make a user account and comment
I think you might like the
Antec Gun Metal Case
since you can take it apart, place the pump wherever and what not. 3/8" tubing will work quite nice.
If you want to ignore the money of water cooling and have fun this case mentioned above will give you the most possible flexability with any number of kits, rads, and tubing size right out of the box. I seem to make the same mistakes over and over when I pick a chassis to avoid spending $$$ and end up forgetting that to lower air flow is to cool more components with water. After moding a "s***" case to get the flow I needed and the holes right where I want them I realised I would have spent the extra 50-60 bucks just to get a case like this! ONE hole in that case and it would suit my cooling setup.
Coming from experiance (e.g. too much money wasted on water cooling trouble shooting) I would have to say don't do it! Especially for a CPU the cost of an entry level Rad, which really doesn't do the job and that's what you're getting on that CoolIT crap, pump, and block is "too much". By "too much" I mean money or fun
. By the way my most recent pump was a defect, caught on fire, and I almost fried my CPU!
Difference of a cpu on water and a cpu on air realistically is next to nothing unless you're using a peltier or you're trying to cool a 65nm quad core with a wicked overclock. I've noticed that with 45nm tech that the chips will be warm (45-50C) and only warm with shoddy air on sane voltages. The gpus on the other hand are beautiful on water cooling and I would recommend water solely for the purpose of keeping your baby nice and comfortable while it churns out pixels. Cheers
