OK this is good info! So guess I should put money towards HDDs instead of RAM.
I'm planning on this server as acting as a:
DHCP Server
Samba PDC/file server/print server
Email Server
Possibly Webserver
And if its easy enough to setup, OpenVPN.
Plus it it will be our gateway, I'll install 2 Netgear GA311s.
I was also wondering if I could use a proxy to block banner ads?
Thanks for your patience,

Craig
