Can't help you much with this I'm afraid - it sounds a bit like Squid's
transparent proxying, but I've never really used it. Can you not specify
proxy settings on the client machines (either manually or via group policy)?

I'd say there are 3 options here:
1) use multiple squid boxes in a load-balancing configuration. Squid's
support for this is pretty good (you can either get each squid box to use
the client machines to load balance between multiple squid boxes.
2) If the problem is HDDs, consider using multiple HDDs in the cache, each
in a hot-swap bay so you can add/remove them without taking the squid
machine offline. There are some reasonably priced SATA hotswap units around
these days and cards to support them.
3) Depending how much disk space is required, consider using a squid box
with a massive in-memory cache (4GB or so) so that frequently accessed data
is nearly always coming from ram, not disk. Don't know how much difference
this'll make - my experience of squid has been that any more than about 4GB
cache tends to use as much IO time finding the object as it does to grab it
from the remote website.

A client's place is running on an XP2800+/512/80GB with about 30 users and
quite a few other services on the same box (IMAP server, etc.) and there
doesn't appear to have been a load problem. HDD seems to have been reliable
- Seagate 7200.7 SATA if it's any help to you. Tend to use them in all
machines for clients - they're cheap, quiet, reliable (yet to have one fail)
and have a 5yr warranty on 'em.
