Client is currently using Netware 4.11

I need to setup a 3 Server Network with 3 Servers

Main File Serve with Backup Exec
Fax Server using tobit
Backup Server - using Rsync (also tol hold some old data)

There are 25 users - they needs access to ALL 3 Servers

What do I buy - just 5 x 5 users
(I was thinking of taking advantage of the OES Infrastrucre Bundle with
GW7 - 4.11 - OES so qualify for upgrade??)
