[mythtv-users] Lower power usage ideas? (for backend)

[Tony Godshall]

Here you can get a double-win.  A fanless power supply by
necessity is very efficient (the less power you waste, the
less heat you generate).  They are kind of pricey but worth
it, I think, if you can afford the extra $100 over the super-
cheap ones.
