Hack a Day brings us a low powered OpenWRT NAS in a tin box.
A detailed blog post which covers hardware and software choices.
For the hardware, I ended up with a fanless MiniITX motherboard Intel D510MO, which has a Atom processor, Gigabit ethernet (all my home network is Gigabit, so it does make a difference). I am also using a 2GB 800Mhz Kingston RAM memory, and both two SATA connectors. The MOBO has up to seven 2.0 USB and one mini PCI Express, in case I want to add more SATA drives in the future.
Will Urbina has posted full build pics of a low power NAS using an Atom processor, HighPoint 8-port RAID card, and eight 2 TB SATA drives.
This blog contains full instructions, including links and pictures of all hardware needed, to build a 1+ TB NAS. Windows XP is used as the software, while a Highpoint RocketRAID hardware RAID card takes care of the drives.
I did some research into building a network attached storage (NAS) server, and bought the appropriate hardware online. I’ll cover the steps I took to build a homebrew NAS server capable of offering 1Tb of redundant RAID 5 storage.
