Building a NAS, Part 4: Assembly!

In parts one, two and three, we went from requirements to a honking big Ebay order of various computer parts. Well, they’ve all arrived, and so it’s time to put our machine together.

Building a NAS, Part 3: Finding and buying parts

In parts one and two we went from a list of requirements to a set of constraints on the hardware we’ll need to buy. In this part, we take to Ebay and turn those vague ideas into a concrete parts list!

Building a NAS, Part 2: Storage napkin math

In part one we got together some requirements, and got a rough idea of the kind of server we’re thinking about. Now it’s time for some napkin math to work out some minimum hardware specs related to the storage on the box.

Building a NAS, Part 1: Requirements

A friend would like a new NAS, with a combo of features and performance that would normally place them in the $10k+ range for enterprise grade storage. I offered to see what I could do with hardware from Ebay, and I figured I’d write down my thought process for this kind of thing, in case it’s of use to other homelab shoppers.
