Stacking Antminers Is It Safe?

I'm trying to stack 3 Antminer S19s in one box. Started with wooden boards and putting spacers in to support them. Can I skip the boards? Can the bottom miner handle the weight? Will heat be an issue? Don’t wanna break anything! Here’s what I drew: https://ibb.co/4dcCYBJ https://ibb.co/hK0L79p I’ve got ventilation on both sides for air flow. Thanks, guys!

What are you trying to do, exactly? Two miners or three in that box? If the box in your pic is your plan, you might see some heat problems. You gotta ensure the hot air has a way to escape. Can’t let it get too hot, right? A double fan setup and ducting could help with that hot air.

I doubt it’ll be a big problem with weight. I’ve stacked like five miners before (not running though) and the frame held fine. Just remember those weren’t powered so no vibrations. But can I ask why you're ditching the wooden plates? Seems kinda risky unless you want an open airflow. If you stack them without that, heat from the top and bottom miners might just circulate inside and make things worse.

I’m sticking with three miners, planning to drill air holes on the box sides. Each miner will get two 150mm holes for air in and out. Wasn’t sure about keeping the plates for noise foam, but they might block the airflow. I’ll make sure to drill at each miner’s height for free air flow. Ask if you have more questions!
