It’s decent for most usecases. The motherboard has two gen5 pcie ports, and it comes with a 1,000W power supply, so you should be able to add a discrete card if you need it.

Sure, you could build your own comparable system, but it’s a nice package at a fair price, assuming it doesn’t go up.

I don’t know, it’s a solid package, 15 bays, decent CPU with good integrated graphics, and not much more than much smaller and weaker NAS offerings.

Can’t get it to connect to Plex, it just fails after authenticating.

There’s a community plugin for self hosted live sync.
