What rack are you using?
Are you selling the rack?
The rack is something I custom built, it's actually both a rack and a plenum, meaning it takes all the exhaust air and isolates it - but you still need to have extractor fans to 'pull' the air out. Works REALLY well, as long as you make sure the exhaust fans have enough static pressure. It actually has a manometer on it that shows the pressure differential between the room and plenum, so it's really easy to see if you need more fan power or not.
The v2 rack you see in the pictures handles 32 miners (4x8) - my v3 rack, which is the same physical size, handles 40 miners (5x8), and is pretty much the limit as far as density goes. The rack itself is about 6 feet tall, 3 feet wide and about 1 foot deep, and is aluminum with fiber board (heat rated) inserts. The v2 rack requires you to remove a side beam (easy) to remove miners, as they slide in and lock from the side - whereas the v3 then kind of lock in place from the front, making them easier to maintain.
We're keeping most of them, but I would sell either of my test ones (one v2 and one v3). I suspect it wouldn't be cheap to ship, even though it breaks down into parts and is just re-assembled. I could also ship it without the fiber board inserts, which you could just get made at home depot, and that would probably drop the shipping cost considerably. If you're serious about it, then feel free to PM me.
