It should have minimal effect on your workshop - for mine it's just 4 screws fastening the backboard of the box to the wall, an 80mm hole I used a core drill head for to get the hot air pipe into the garage/workshop and a 6mm drill hole to take power out from a normal 3pin socket to the PSU. I just used a 3m kettle lead, cut the moulded kettle-type plug off and connected it up to the PSU. It makes it easy to power up or isolate from the inside, and the Bluetooth app means I don't have to open the box to change any settings.That's brilliant insight, thank you! I am always pained to touch my workshop as the previous chap basically had it built and then never so much as put a drawing pin in the structure lol.
