Build the ultimate DIY network storage machine using free software, a mix of hard drives and an old PC.
We love a good FreeNAS... who doesn't? A Network Attached Storage box solves a problem lots of folks have: there's never enough space for all your data. Whether your storing documents, digital photos, music, movies or games you'll always need and want more space.
All you need is a machine with an Ethernet card that can boot off a USB thumbdrive, and the free free unRAID software.
