Question : Problem: Measuring for a Server Rack

We're a small shop, but we finally have enough servers to get a rack.  Problem is, only one of our 6 servers is a rack mount server.  The rest are towers which are sitting on shelves in a closet.  Can I mount these tower servers to a server rack?  What would I use?  And, is it safe to get mounting kits that might mount these servers sideways and make them rack compatible?

Answer : Problem: Measuring for a Server Rack

Yes, you could mount it all (my guess is that you want to save some space), but think about if you need to access one of those computers inside... How much time do you need?
You should watch about air flow, also...
My personal advice is "don't do it"
