Ahhh, I don't know anything about our partner-facing websites, sorry
In the area that I'm in, I can think of a couple of recent case studies that showcase our use of our own technology:
"Exchange Server 2003 Site Consolidation"
"Next Generation Headtrax"
And while finding that Headtrax reference I stumbled across a page with a LOT of other Microsoft showcase papers - check it out! "Microsoft IT Showcase"
