NAS Killer v4 LGA1155 Completed Build

After losing data to a few dead external hard drives over the years, I decided it was finally time to make the move to a proper NAS.

For now, my needs are pretty simple - just needed for data storage and network share for Kodi streams. So, I started with a hand-me-down Dell Optiplex 790 I had sitting around and threw in a few drives.

Issues -
Once I installed the EverCool Drive Bay, I couldn’t get the front panel back on. Some sand paper and elbow grease and it now fits like a glove.
Drives in the EverCool Drive Bay are hitting ~45 C after hours of reads/writes. Still waiting on the fan leads to arrive from China. Should be within the next week or so then I can get the fans wired up and replace the loud stock ones.

Planned upgrades -
Purchasing SAS controller, SAS > SATA/SAS breakouts, and SATA Power splitters in order to add a few more drives.

Big thanks to everyone on Discord for all of your help through the process!

Successfully set up Sonarr + Radarr feeding DelugeVPN. Things are running without a hitch.
Also succeeded in pissing off the wife with too much time on the computer looking up how to do all of this stuff.
Overall, I’d call this mission success.
