Mixing Dangerden, Aqua Pc, and Swiftech...Will these componets mix?

Hi,
I was planning on getting an lian li pc75 and going all out on a watercooling system. My current one is just not enough, despite getting me 4ghz. I was looking at aqua pc, and their stuff is gorgeous, but they do not make any tec units, which is a must have. So i was wondering...would all these componets fit together and would their be any major problems with them?

aqua computer res = 73
aqua computer 3 fan rad = 113
aqua computer rad grill = 37
aqua computer res mounting bracket = 13
swiftech mcw500whatever cpu tec block 226w = 110
danger den maze 4 gpu tec 80w = 59
172w tec unit to replace 80w with = 30
meanwell 12v supply= 118

currently have eheim 1250 pump

one thing that I was wondering about was the tubing size....aquapc does metric tubing, and i know swiftech is 3/8id. So if I got the swiftech and dangerden with 3/8 id tubing, that *should* fit with the aqua pc gear too, right? I'm a little bit confused about the europen tubing size..

also, with that setup, would my eheim 1250 be enough or should I invest in the swiftech pump? Any and all help would be appreciated.

I believe the 3/8 will fit. Definately get the MCP600 for the restrictive tubing. I have one and it is VERY quiet.
