Rolling a rack on carpet

[Dean Johnson]

Just put the rack sideways. Then you have access to the back and front
and don't need to move it at all. Of course it isn't as pretty, but
ultimately more functional. 

At one point it occurred to me that you should just install cluster
nodes backwards, save for initial installation, you often don't have any
use for the front of the machine, except for the power switch and things
like drive lights. Since you have the cord right there, you have no need
for the power switch. It was just a matter of putting led's in slot
blanks to get the indicator lights.
