This is called "Beowulf-at-night" or BAN.

Its not "hard" to do, though how do you handle jobs which run longer 
than usual, or machines that get wedged into some odd state?

You might wish to look at some offerings from Platform Computing.  You 
could tie those in with Cygwin or similar, and have a "unixish" place to 
run code while retaining the desktop.  You could also look at things 
like United Devices.  Just beware that there is a bit more of a 
philosophical buy-in with that approach, and it is a bit more proprietary.
