FreeNAS is a task specific operating system designed to be used in Network Attached Storage (NAS) devices. It’s built using FreeBSD as the underlying OS which lets it have some fairly low power hardware requirements. For example the Dell I used is an old Pentium 4 1.7 GHz with 512 MB of RAM and it runs like a charm, granted I don’t put a lot of demand on the box in the way of concurrent transfers or running processes. It’s worth mentioning that the recommended way to install FreeNAS is to install to, and boot from a USB thumb drive. This is the recommended method so it can save as much hard drive space for data storage, but even though it looked like I could boot from the thumb drive like a hard drive in the BIOS I had trouble getting it to boot so I installed the OS to the 160 GB hard drive with partitions for the OS and data. Here’s the parts list with some specifics after the jump.
- Old Dell Dimension 4400 – bought at university surplus sale, $5
- Various old IDE hard drives I had sitting around – two ~20 GB; one 160 GB, probably cost me something at some point…
- USB thumb drive – “borrowed” from family, free
