A few questions about building a rack.
So I'm planning on building a rack system as I plan to buy more bps, and I know it's way cheaper to build your own. This is how I plan to build it using this guy's method- https://www.youtube.com/watch?v=WEbZsABO-dc now my questions are, for heat tape would it always be in the back? Also is it safe to keep against the material? Would I just aluminium tape it down or is there something specific I need to do? Does it matter if the bottom of the racks have little holes underneath(as all the ones I found had). Is there anything else you could add that might be beneficial to know outside of what he says in the video? I'm not really good at building things, I've seen a lot of DIY racks and they just have a lot of stuff in them I don't understand. So, please with what you say specify as much as possible. Side question, can any thermostat go to any heat tape or do they have to be specifically for it?
