An Intel system with a Sandy Bridge or Ivy Bridge CPU and a H61/67/77
Q61/67/77 would draw about 20W idle without harddisks, OS on an SSD
and a Pico PSU or any other efficient PSU. With some tweaking you may
even get a little close to 17W. When adding harddisks a rule of thumb
would be that green 3.5" drives draw 4-6W idle and "normal" 3.5"
drives 8-9W idle. Laptop drives are interesting for low power builds
as well and may take little more than half of the 3.5" drives. These
numbers are based on personal experience where I measured consumption
using a wattmeter (Voltcraft Energy Logger 4000) and experience shared
in fora on this topic.

So getting a system that stays well under the 100W mark is very
feasible. Under 50W should be relatively easy as well as long as you
limit the number of harddrives. The version of MythTV should be
irrelevant when it comes to power consumption. For Intel based builds
http://lesswatts.org is an interesting site offering power saving
tips. AMD based builds can be very efficient as well, so it is
definately not a must to go for Intel if you want something power
efficient, but in fora there is less information on AMD builds
compared to Intel.
