Silent NAS/router based on Lian Li PC-Q08

I´m going to build myself a NAS/router based on a Li Lian PC-Q08.
Going to use FreeBSD as OS. (ZFS?... don´t know yet)

This is my reference blueprint.

I have ordered:
* Lian Li PC-Q08B
* Cooler Master Silent Pro 600W
* Corsair 4GB (2x2GB) Value Select DDR3 1333MHz
* Intel Core i3 540, 3.06GHz
* Zotac H55-ITX Mini-ITX-C-E



And yes, I will disable the blue led in the fan.
