I've seen a few pictures of peoples conversions, but was interested if anyone has been able to put them into a 4U enclosure to mount in a standard rack?
If so how many were you able to fit in and what about power supply location.
Thanks

What I find out, is that it's cheaper and easier to just buy a metal storage rack like this:

Then you just put Ants on them (up to 5 in a row) together with server PSUs (what I do, is I put those PSUs on top of ants).
