Just a DC with DNS, DHCP services? No other applications, no file serving requirements?
Spec a single CPU, 512M-1GB RAM, PERC, and 2x15kRPM 18GB drivers in a RAID1. Also think about a redundant power supply. Your choice of 2650 or 1750, though I think you'll find that once you add a RAID controller and second power supply, the costs equalize (and the 2650 might even be a little cheaper.)
Before anyone jumps in on the single RAID1 array, yes, I realize that in an ideal world your DC will have two sets of drives--with your AD database on one and your logs on the other for performance. But based on the fact that this domain is so small, I don't believe it justifies the extra cost.
Keep in mind that backups are important, and no dell rackmount currently supports an internal tape drive. However, all of the tower units DO and they come in rack configurations, though it'll cost you at least 5U of rackspace.
