Exchange Server 2003 Loadfest?

I just got done tweaking our site to feature the Exchange Server 2003 Loadfest.  I've personally never heard of this before, but from what I've gathered is that you bring your own server to our center, and basically walk through a one day course with your system so when you get back to the office you've been there done and done that.  Has anyone ever gone to one of these?  Has anyone taught one of these?  Does anyone actually rip out their rackmounted server and drag it in? :-).
