It's not a bad way, but it's not the most efficient by a long chalk.

For my always on services I run a SheevaPlug with an external USB HDD.
At idle, the pair consume 3W, with 15W being about the peak.

SheevaPlugs used to have the downside that they destroyed a power supply
about every 9 months by letting the magic smoke escape. Both mine have
now had replacements which are supposedly more robust. So far so good.
