Btw there's also the Celeron SU2300 which has a TDP of 10 W and is
about twice as fast as the N330 Atom as you can see e.g. here:
http://www.notebookcheck.net/Mobile-Processors-Benchmarklist.2436.0.html
(even tho it only runs at 1.2 GHz.)
I know this because I had a similar problem as you and now I'm in
the process of setting up this little box called "ZOTAC ZBOX HD-ND22":

It was about EUR 200 without disk/RAM, and the only drawbacks I found
so far are:
a) its not fanless (although pretty silent),
b) it only supports usb keyboards/mice,
c) the bios seems to be a little buggy when booting from the internal
disk using FreeBSD's bootcode/loader (there's a long-ish delay
before loading each bootcode/kernel/kld and the usb keyboard
doesn't work in that case either until the kernel is started)
booting the install image from an usb flashkey was much faster
and the keyboard worked too. I have yet to try putting grub2
on the internal disk and booting FreeBSD using that, or if that
doesn't improve things putting the boocode/kernel on a flashkey
- and
d) at least 8.2 doesn't know the onboard Ralink RT2860/RT2890 wifi,
(I wanted wired anyway and the onboard nfe(4) seems to work)
e) it doesn't have audio line in, only line/spdif out and mic in.
(of course you could connect an usb soundcard.)
BUT:
- vdpau with xbmc etc works pretty well including for 1080i with
half temporal deinterlacing (no temporal spatial tho since this
seems to be the `old' ION),
- unlike on miwi's box the amd64 nvidia driver _does_ work with
8 GB RAM,
- the cpu has vmx too so if you want you can even run vbox with
amd64 guests, and
- after some patching (more on that later, I mainly wanted to let
you know about the SU2300 before it's too late :) I now also
got vdr working pretty well on the box using vdpau and/or vaapi
and a "Technotrend TT-connect S2-3600" usb dvb-s2 tuner.
HTH,
