MSI Pentium M Server - Killer Small Network Server or Brick?

Is the idea of using a Pentium M powered system like the MICROSTAR P1-104A2M for a small, economical and power efficient server a stroke of genius or of madness?

Obviously a system like this is not going to win any performance tests, but it should be very easy on the wallet (both for purchase and electrical operation costs), and more than sufficient for a small network that just needs a file server.

Am I mistaken? And I am not affiliated with MSI.
