RAM is by far the largest resource you can't possibly have enough of. For that number of users, I'd go with more if you can.

A quad core Xeon *should* work. One thing to remember is that your CPU usage will vary depending not on how many total clients you'll have but how many *simultaenous* clients you'll have accessing the system at a given time.

Another considering is the speed of your hard drives. 10000 RPM SATA/SAS or SCSI would be needed and you'll probably want RAID as well.

Check the Zimbra site (in the wiki and forums I believe) for more information on dimensioning Zimbra systems with many users. Most of the recommendations there are from real world scenarios.
