Yeah, I'm thinking a warehouse with two large garage doors rather than one so I can do something like intake for one door, have the miners lined up in the middle, exhaust for the other door and create a "U" if I were to visualize the airflow.

One space I was looking at to move my operation into was a smallish warehouse with a garage door on each end (part of a "warehouse/shop" building complex).

The primary reason I decided against it was that there was no "man door" at all, and my knees don't handle stairs reliably any more - both garage doors were at "pickup/semi trailer" height.

Airflow would have been trivial to set up though - louvered "inserts" under each door and straight-through airflow.

Ah. Yeah if I go with a warehouse it must have not only the large garage doors but a small standard sized one as well, because I'm trying to come up with a solution to stack fans on top of each other to maximize the space of the door and not just have one row of fans on the floor. I would find a way to chain them all together along with the door to the ground, so you wouldn't be able to get in or out of the large doors for better security. I'm sure there is some industrial fan out there that is meant to be stacked for what I'm looking to do. If anyone has heard of anything like that, post it here!

I'm considering an investment of about the same amount for 20 S9's, though I may also have to look into L3's after reading the last few posts. I'm not particularly experienced, but I've run preliminary numbers on the S9's and they seem like a solid investment as long as they last for longer than a year. Does anyone have any info on their longevity, or is it too early at this point? They've been released for near a year now, so if they're not sturdy enough to consistently hit the break-even point I'd think that should be starting to become clear by now.

I'm not sure about renting a warehouse, it'd be a bit expensive in my area and more of a hassle to operate. Just how hot and noisy are these miners? I'd like to put them in a building separate from the main house on my own property if possible, as that would also let me install solar panels and generate a portion of the electricity for the system as well as generating income from SRECs to offset the remaining electricity cost. I'm in the Northeast, so the climate should be a bit more friendly to this kind of thing, but might need to look into insulating a building for sound if they're extremely noisy. My electric costs are roughly $.09/kWh, but with solar panels I'll be able to yield an extra $200 in SRECs for every 1000 kWh generated that way. At that rate, having air conditioning might be feasible if necessary; noise would definitely still be a consideration though, and in fact even more so. It looks like the S9 runs at about 77 dBa, which would put 20 of them at about 92 dBa. That might not even be legal in a residential area without some serious noise reduction. https://www.youtube.com/watch?v=LvzP4g1bfh0 seems like it could be a solid strategy, though 20 in that kind of setup might not be possible without expanding the space I was thinking of using. Any thoughts on all this?
