OCD guy

Hi guys, I've just ordered a Core P5, but my only concern is pump and res compatibility. I know that certain Thermaltake stuff fits but I don't wish to use those watercooling parts. I appreciate Thermaltake staff may not condone promoting other manufacturer parts, but I just want to know ultimately whether the case has "universal" compatibility with the most common watercooling pumps etc I've read a few build logs and people have drilled their cases, I am not comfortable drilling a brand new case, and would be surprised if compatibility out of the box is ONLY for thermaltake watercooling parts. Thanks
