WSUS Storage Capacity Sugestions

I am installing a WSUS server in the school system I work for.  I am very new to this setup.  I have been reading the Windows Server Update Servcies 3.0 SP2 Deployment Guide.  I am trying to decide on a reasonable amount of HDD space to allocate for storing the Updates.  We are useing the following environment.

We will have an Upstream Server at our Central Office that will pull the necessary updates from Microsoft.  This Upstream Server will then Replicate these updates to a Downstream Server located at each school.

Our network consists of the following Microsoft Products 2000 Server, Server 2003, Win2k, WinXP, Works 6 - 8, Office 2000 -2007, SQL 2000, SQL 2005

And, odds are I am forgetting something plus we would like to allocate a little extra space to allow for future growth and upgrades to Win7, etc...

Any Suggestions on storage space amounts would be greatly appreciated.

30-40 gig is the highend of space that WSUS will use. You shouldnt need any more than that.
