I just bought the Antec Mini P180 Black Steel MicroATX Mini Tower Case and foolishly did not even consider the decresed size factor in regards to liquid cooling!
I am a total newbie to this, ive built many computers in my life but none with liquid cooling. Will the cases size have any dramatic effect on using liquid cooling?
If so what compact pump would fit in it? I was gonna do a custom metal job to mount the radiator on the outside of the case. Which leads me to wonder, if done with excellent craftsmanship and correctly how stable are liquid cooled loops to movement, like transport in a car?

I did see the " Liquid Cooling · Information/Guides & Reviews/Tests & Galleries" but much of it is older posts (2004-2008) and we all know technology can change within months, or even weeks!
thanks for your expertise
