I’m using this exact tower still. I inherited it for free from work. I swapped the CPUs to some lower TDP L5640s and put an H710 in to allow a 6x4TB array and a Quadro P400 for transcode.
It has no problems pushing 4K HDR streams in my house, or several 1080p streams remotely to family and friends.
You can definitely find lower power solutions, but probably not at this price point with the 6 Bay storage included. All things considered it really doesn’t draw that much power, but I might be biased with my inexpensive solar electricity.
I bought Dave the Diver.
