I want to setup a Windows Home Server in my house, however I want to have the hardware that consumes the least amount of energy (having a pc on all day long can get expensive!), and also with most flexibility regarding location.

I live in Mexico and unfortunately I havent seen any of the prebuilt small WHS machines, so I thought maybe a netbook could do. I know it doesnt need much CPU power or RAM, but I dont know if a netbooks way too weak for it (im thinking a netbook with 1gb of ram or something around that).

For the storage I would add external usb hardrives that I already own.

Would this setup work?

If not, do you think it is possible to built a ultrasmall, wireless enable pc that spends as much electricity as small laptop/netbook?

There's something called a nettop that might suit your requirements better than a netbook. It's a small desktop computer that runs off the same low-power processor as a netbook, and would probably work as a home server. – ephilip Dec 3 '09 at 16:36

Technically, it should work...

Personally, I wouln't.

For half the benefits of WHS, you want RAIDed hard drives that are connected 24/7, not USB ones.

Again, it would work... but there is little point when you can use something such as Freenas if you just want to backup a few files... WHS is a lot more than that.

well the USB drives WOULD be connected 24/7. And I want it to automatically do incremental backup on all of my family members'PCs. – bangoker Dec 3 '09 at 16:28
I understand, but USB drives are terrible in comparison to hard drives connected through SATA..., for a start, a lot of the caddies keep them powered up all time and have no power save features which is counter to what you want... I just haven't seen really good ones. – William Hilsum Dec 3 '09 at 16:44

I just purchased an HP LX195 which has netbook spec hardware in a small footprint tower.

They are only about $250 and can be expanded with usb hard drives.
More than adequate for my modest requirements.

Why not do it? Actually some good hard drives can power down, like the ones I use (Samsung 3G) - these are highly efficient and power down when not needed.

They cost around €89 for 1.5TB, which should be equivalent to roughly $100.

You could also make use of a Nano-ITX or Pico-ITX board: these small platform are even less power hungry. My main PC is an Atom dual core and the netbook a single Atom. These processors are fine for modern day use - for gaming I just use my PS3.

i'm running WHS on a Eee pc 701 8G (Celeron M, slightly overclocked to 1035 MHz with 2 GB RAM), works like a charm.
