Hello all, n00bie here, be gentle...

I've been wanting to rackmount my old, modded-up 7600s (G4 heart now) and Gigabit Ethernet Macs - but not as in slap some rack ears on the sides of the existing cases - putting them in a new, low profile 19" rack case. Does anybody know if this animal even exists, and where one might get one of those?
