as Shortalien said, put a drain port somewhere.. its easier to pull out the loop if you have one.. I mean SOOOO MUCH easier. and as TSM106 said just get the mounting bracket so that you can mount the pump on the case wall.. I think pump upsidedown would work in theory coz of gravity will just pull down the coolant to your pump but I doubt its asviseable to use it in that orientation.
and for the rad at the back you can just test fit the rad for your top on it and see if it fits. if it does then delay it and buy another 240 rad so that you don't have to drain it all over again just to add another 240 rad.
