RAM is the single most important issue for a name server. But for a
caching only server, this shouldn't be too much of a concern either.
All cached DNS information stays in RAM, so the more the better -
but don't go crazy with it either.
Disk space is not important, assuming that you have enough to hold
your OS. If you build BIND somewhere else and then simply copy the
executables, BIND is quite small.
CPU speed is not critical. BIND-8 and BIND-9 appear to require more
CPU than the old BIND-4 which ran quite will on slow '486 systems.
But this shouldn't be too significant.
I would suggest a mid-level Intel/AMD system running OpenBSD or
FreeBSD. I'd equip this box with 128MB RAM and a smallish (1GB) disk,
and a good PCI 10/100 ethernet card. Absolutely nothing special. Look
for reliability rather than speed. These systems are cheap, and

Definitely get a cpy of Cricket's "DNS & BIND", do this "right away".
Also, take a look at
which addresses running named in a chroot/non-root environment.
