Brian and Andrew of Ejelta LLC (creators of isbndb.com) donated a blade server to perl.org. It's a few years old, but still quite capable. We're not totally sure what we're going to use it for once we get it running. It's a RLX 300ex.
Ask and I spent yesterday afternoon playing with it, and have it mostly figured out, although we need a little more time to get it just right.
The management interface on it is sweet (to use one word.) Built in console server, remote management, etc all in a very snappy and easy to use web interface.
Blades. They are the way of the future.
