Good timing for this thread. I just finished consolidating 2 computers worth of fun into 1 newer computer that can do it all. I sold my wife on the idea with electricity as the reasoning.
In the end, it uses 30 watts less, which is not as much as I had hoped. That's about $5 a month.
180 watts with an i5-13400, 9 spinning disks, 1 M.2 SSD, no extra GPU, 24 port switch (powers 3 AP's), modem, Mikrotik router, and a large UPS. I wonder if the UPS uses any power as a trickle charge for the batteries.
