Howdy, I have been using a old ClarkConnect box at my home for about 6 years now. I don't need a ton of processing power so I used an old Dell with a Celeron 2.4GHz processor. It's done a good job just running in the background. But lately I have been on a saving energy kick and I have been looking for ways to cut my electrical cost. So this server is on the chopping block.
As I searched for a low cost energy efficient replacement a coworker forwarded me an article on the Raspberry Pi. http://www.raspberrypi.org/ Looking at this makes me start thinking how I could make this $35 dollar card work for me. It has one network connection so I would need to use a USB to network adapter if I am going to use it as a firewall/router. Luckily it has two USB connections so the other would use a USB to SATA adapter so I can still use it as a file server.... Then it has possibilities. I don't know it ClearOS supports the SoC iBroadcom BCM2835 and ARM1176JZFS chips and processor. Also I would need to find compatible sata and network adapters.
What do you think is it doable?

I think it did support a Pi with 32 bits for a while. The installation process would have been convoluted, starting with a Centos Minimal install then converting it to ClearOS. Then the ClearOS ARM build system failed and it has not been fixed. I tried installing a 64-bit FC and converting it to 64-bit Centos, but did not even succeed with that and there is still no proper 64-bit Centos build. The main stumbling block is the boot loader, I believe. Anyway, until Clearcenter decide to restart building ARM packages, I think we are dead with this one. -

If you are trying to do this with ClearOS, I don't think you have much chance. Firstly, and most importantly, it uses an ARM processor whereas ClearOS is x86/x64 architecture only.
You may also have problems trying to manage the device because of its restricted port capability although it says keyboard and mouse will work with a hub, but if it can recognise a keyboard, disk and USB stick/USB CD-ROM all connected at boot up then you have a fighting chance. You may also be able to do away with a hard disk if you an SD card instead but this will limit your storage capability.
As a currently low power solution you could look at some of the more recent incarnations of the Atom motherboards which use more recent north or south (I can't remember which) bridge chipe with better low power graphics. These machines can idle at 15w (and my server spends most of its time idling). The issues with the atom are that most are single core and I don't think they generally support x64 instructions. This will stop you from going to ClearOS 6.x.
In reality you can build the heck of a powerful system which idles at 25w - see here. You can also speed limit most motherboards using CPUSpeed so you could lock this board at 25w. I think there are other lower power Core i3 and i5 processors now available so you may be able to reduce the idle power even further.
My own set up uses an AMD x2 5050e, 2.5" disk, no CD-ROM, pico-PSU, dual-port NIC and so on. I also limit the speed as I mentioned above and it idles at between 30w and 35w. Start up is up to 100w but as soon as cpuspeed kicks in it drops right back.
