My first NAS build eBay + FB marketplace (Australia)

Down here in Australia pricing on the NAS killer parts is always out of whack compared to the US. Importing parts usually doubles or triples the cost.
So I tried for as cheap a build as I could using second hand parts and eBay.

The bulk of the components came in a Facebook marketplace machine. The drawback was no HDD cages or modular PSU cables. The previous owner must have sold them off separately when he first built the machine.

I think I found a pretty great deal on HGST 6TB SAS drives @~107.50AUD a pop. Certainly the cheapest i’ve see on eBay so far.

Total $1,785.92 $1,271.37

I’m still waiting for the SAS expander and SAS>SATA adapters to arrive.

I’m not entirely sure how to calculate or judge how capable the machine will be in terms of Plex transcodes and VMs on unRaid. But it seems to be like it should to the trick handsomely.
