Second part to this, I wanted to build my own NAS (Network Attached Storage) system instead of buying crappy overpriced ones. I'm using once again a unix distro based on FreeBSD, called FreeNAS. It's a very powerful NAS software that works better than any thing I've used before. It prefers software raid and uses the ZFS file format which is better than anything windows or mac could do. Most of the storage is media such as pictures and movies. I'm using XBMC as the media center software to stream it.
Specs:
Old Velocity Micro Lian Li Case
Gigabyte GA-G41MT-S2PT LGA775 board
2 x 4GB DDR3 1333 Gskill Ram
Cooler Master Silent Pro M600 PSU
Core 2 Duo 6400 2.13GHz
2 x 2TB Western Digital REDs in Raid 1
