Not rackmount but I was at a client where somebody used 110 blocks one cable in the bottom other half in the clip. I don't know what the speed or integrity is but the client says it is working.
Yes, there are 66 blocks that are supposed to be CAT5e too but I've never seen what the outcome is when you go to certify. Besides, where are you going to put all this stuff if the customer doesn't want it on the wall? Throw it up in the ceiling?
