I noticed one multithreaded benchmark on that page (Cinebench R10 32Bit Multi), and the difference there is a factor of 1.55, a bit more than 50% faster. (And another advantage of the SU2300 is it has vmx (vt-x) and can take 8 GB RAM.) > > The Atom will be more than enough for me.  There are several > > fanless (!) mainboards with a dual-core Atom (330 or D525) > > that have the ION chipset with full-HD MPEG acceleration > > via VDPAU.  I'll probably combine that with an SSD in order > > to get a completely silent system without any moving parts. > > I have a couple atom/ion boxes which I use for dedicated htpc/hdtv. > Works great.

(Hi! :) The webcamd and lirc ports have been updated now so testing a remote + sshd only setup should at least be possible for `normal' operations. (i.e. outside of things like single user mode and setting up the box.) Here is my page with links and vdr ports etc again: http://people.freebsd.org/~nox/dvb/ Juergen
