If you have the room for it he XP-120. The light weight should clinch it for you if you are worried about trasporting the PC. Get a variable resistor for the fan so you can play about and find the perfect noise/temp levels for you.

It seems like you won't have much room for that huge cooler as the CPU socket is quite close to the PSU. The BQE is pretty cramped inside so I don't see it fitting. Someone else will may have experiance with this or a similar set-up.
