Running computers that are left on 24/7, whilst not expensive, calls for a little thought.

So... I'm thinking of getting an Alix Board to replace my router, (currently an old PC running OpenBSD).

Once I have bought a power supply, CF card and enclosure, I'm probably looking at around 150 quid but should get that back in a year or two as its typical power consumption is around 3-5W. OpenBSD installs without problem.
