I am using this mobo in my kitchen pc at the moment.

I am also using an earlier version of this mobo, the D201GLY2 as my server.

Excellent setup for a home server.

I , until not to long ago, had a great home server on a P2 333 with 512Mb ram running SME server (Linux) 24/7. This really goes to show that in a home server it's easy to jump on the overkill wagon.

The parts you listed will be almost dead silent and have a low power consumption. After reading this thread I think it's time to build another home server.
