I have almost exactly the same setup (except that my mini is a
core2duo 1.83) and I haven't had any problems whatsoever with the disk
io. All my recordings are on the external disk, everything else is on
the internal hd using Arch Linux.

I've had it quite happily recording two programs while watching one on
the same machine and one on a remote frontend. Although I haven't had
a chance to play with multirec yet, everything I've seen thus far
leads me to think that an extra stream or two probably won't be a
problem either. All in all a great, small, quiet combined
front/backend setup (and home server for that matter).
