OK I'll math it.

Assuming there's only 1 mining board deep per shelf, there are usually 6 boards per shelf, most "racks" in the pics appear 6 shelves full, there are at least 16 "racks" on each row on the left half of the room and 19 "racks" on the right half. There appears to be at least 18 sets of "rows" of racks on each side of the room (although we can't see whats behind the camera of course).

So we have:

Left half of the room: 6x6x16x18 = 10368 mining boards
Right half of the room: 6x6x19x18 = 12312 mining boards

= 22680 boards (assuming 100% occupancy on all racks/rows as shown in close pics)

So if each board is like the batch 3 product boards then they should be apparently 750 GH/s each

So 22680 * 750 GH/s = 17010000 GH/s = 17010 TH/s = 17.0 PH/s

The current total network hashrate estimate is: 55.5 PH/s (https://bitcoinwisdom.com/bitcoin/difficulty)

So following the assumptions I've made for these calculations, this room would accommodate 30.6% of the total network's hashrate.

Please don't get shitty at KnC only based on my back of the napkin estimations.
