Looking For NK4 Parts List Feedback

This is my first scratch build, I’m looking for a Plex server and NAS for backing up other computers on the network. Planning on running UnRaid. I believe this pretty much follows the “ultimate rack” NK4 but just want to run it by the gurus here before I start spending money. I believe I need SATA cables still, anything else? Anything I’ve over-spec’d and can tone down?
