Dexter you have forced me to upgrade my 10GH/s sawhorse juryRIG monstrosity.
I thought your rig was so cool that I showed it to .... wait for it .... my wife.
Her response was "Why don't you do that?". DOH!

One question. What kind of AC unit.
I mean if you are pulling 12KW at the wall that is >40K BTU/hr.
Hmm. I'll bet you are too far away from me, since I don't want to ship it, but I have a rack for sale. It is a nonstandard 27" from post hole to post hole horizontally, and that would make it easier to fit miners in (instead of the usual 19").

Wonder If I ought to fill it with miners though?
EDIT: It is 30 U high.
