You will have problems priming the pumps with that setup. You need to put them on the bottom of the case below the resevior, then have a tube to the cpu, then to the radiator, then back to the resevior.
With your setup, I dont think you will ever be able to prime the pumps without leaning the case really far foreward.
Wait, you have all that stuff on your case... why not make an external thing for it? I can make you a pic
