I decided I didn't have enough NAS in my life...
So my last DIY NAS build developed some minor issues and I decided it was time to start over. This time around I elected to have an open air build and integrate it into the bottom of a shelf, meaning everything thing you see will be hanging under the shelf it's current mounted to. This way I can mount it to a wall in my storage room and put a monitor and keyboard/mouse on top for easy access.
None of the parts are new, everything is stuff I've had for awhile, though the drives and the power supply came from the previous NAS build.
Specs:
CPU: Xeon X3470
Mobo: Gigabyte ga-h55m-s2v
Ram: 8gb DDR3
GPU: GeForce GTX 745 4gb
PSU: 400w SFF power supply.
Storage:
4x 1tb Samsung Enterprise HDDs
A 720gb 2.5" for Windows 10.
A Startech hot swap bay that takes 2.5" SATA HDD/SSDs in external hot swap cases.
Extra: a 4x port USB 3.0 add-on card to supplement the 8 USB 2.0 ports on the motherboard.
