Honestly I'd go for a 360, even for CPU only.
If you're going 240 you might as well get a H100i or something. A 360 rad will allow you to spin your fans slower = less noise. If you spin them at a decent speed you'll also get way better cooling performance. With a 360 you could even put your GPU in the loop as well, but I'd get at least another 120 then as well.
The pump is good, but with that reservoir it's going to be annoying to put it together...unless you use a lot of tubing.
I'd go for an EK X-res 140 or bigger/smaller. I have one and I love it. You just get a D5 vario without a pumptop (60$) and screw it into the X-res and you have a pumptop + reservoir combo all in one.
