I'm installing a main lug in my basement to bring in 240v for my antminer a3. I just popped open my main breaker for the first time and I can say without a doubt I wish the electrician who did the initial wiring would have made it as organized as yours did hahaha.
Also, why are you using shelving instead of racks? Seems like some racks and pdus would take up much less room.

Probably cost. From the looks of the pictures, he has lots and lots of empty space in his warehouse. Those shelving units are probably around $100 a piece or so. Way cheaper than even used racks.
I'm using similar racks because I had a ton of them from my prior business.
You can get 42U frames on ebay for $100. I'm going that route.
Keep in mind though, you'll need rack mount kits for those servers. If the servers don't come with them, you won't be able to drop the servers into the rack.
