Do you realize that having tubing come out the top of the reservoir will required an M2 to G1/4 adapter? also you would probably be better off buying the pump and res separately as they will cost less and that combo is more designed to have the inlet and outlet at the base of the res where the pump is. You also should be thinking/ planning for angled adapters, fill ports and drain ports to make the loop easier to use.
I recommend buying all your larger parts, eg rads, res, blocks. And planning out your loop before deciding on fittings.
Finally, have you decided on fans for the rads? best to look at gentle typhoons or a few others with very good static pressures. http://www.frozencpu.com/products/10323/fan-674/Scythe_Gentle_Typhoon_120mm_x_25mm_Fan_-_1850_RPM_D1225C12B5AP-15_Hot_Item_.html?tl=g36c15s60
