Hi, I don't know what number of users you have to connect to internet, but I have my squid mounted a RH9 in PIII processor, 512MB RAM and 9 Gb HDD for a system of 500 users and don't have problems with memory or disk space. I think that Squid is the best program to do this and sarg is a good tool to do reports. Saludos. Xabier.
