I would go with the P180 dude
Its a great case, I've read loads of good reviews, and its got padded side panels to make sure that it stays quiet. Its also got an awesome layout, and your paying for quality
However, if you want to go with Lian Li I can't stop you - Lian Li cases are meant to be awesome anyway
Just go for the case you want to stick with, even if it costs that bit more. The case is damn hard to change - don't forget you've gotta take everything out and put everything into a new case - it will also be the first thing of the PC and probably the only thing which everyone sees and you don't want to get a different case and then wish you had the P180
I myself bought a Centurion 530 and have been happy with it for over 2 years - it is one of the only parts of my PC left when I first built it left
Personally I prefer the Silver version of the P180 anyway:
which is in stock
Have you thought more about getting an Accelero to cool your graphics card and keep the noise down?
Also, don't forget fans and if you want an utterly silent case get a fan controller - Overclockers do the Akasa Fan Control Junior (http://www.overclockers.co.uk/showpr...odid=FG-021-AK
) which would do you nicely, but don't forget if you get a case with a door about clearance with the dials
For fans, I would recommend the Sharkoon 2000 series which are meant to be very quiet - Akasa Ambers are expensive but quiet, but get a fan controller if you want to make them perfectly silent.
