I can second Sander's recommendations. Disk size use depends on logs 
mostly, the rest is rather fixed well beyond 1GB. CPU - 2-4 will be OK.

Mem is a longer story. 2GB VM minimum, 4GB recommended, you can use up 
to 8GB VM, above it makes rather no sense.

With RAM the main user are passwords processors (i.e. checking or 
setting up a password). But you can fine tune the settings, and recent 
versions of Unity manage memory wrt this quite well. In short - the more 
memory you have, the more secure password storage settings you can have. 
Also note that users count doesn't matter, number of concurrently active 
users (e.g. logins, sessions, logouts, admins, ...) matter.

Below 1GB per unity (note OS use!) it slowly starts to be harder to make 
it working, requires config tweaking.

HTH,
