My idea of a dream network is cost efficiency.
Server:
One Dell T210 with a single quad core proc, 12G RAM, x2 300G 10,000rpm SAS drives in a RAID 1, SBS 2011 as the OS.
Workstations:
6 Optiplex with 4G RAM, smallest 7200rpm SATA drives available, Windows 7 Pro, Office 2010 Home and Business, 19 inch monitors, onboard graphics card.
Estimated cost approx. $8000.
