How's this: Pentium-Pro 200, 64Mb RAM and a 4Gb UW-SCSI 10,000RPM HDD, FreeBSD *cough* 4.7.  Runs an authenticating squid cache/filter (bannerfilter) for the office and feeds off a 4Mbps SDSL connection; all users have seen the full 4Mbps at the client end so there's no bottle-neck with our Squid cache.  Average system load is < 0.20 and most of that is nmbd/winbind authenticating with our ActiveDirectory and the filter.  Usually there are 10-15 unique users with each user running multiple requests (IE/Netscape, Win2K web updates etc).  Below is a snippet from last night's system report:

These are all the processes associated with Squid authenticating with winbind.  The system has been up for 6 days now (rebooted due to kernel recompile - uptime was 128 days before that....dammit!).

So yeh, with 2 users and the system spec you describe, you should be fine :)
