Что это за конструкция?

@l29ah Спалю за миску мюслей.

I only rent one small room (the shared area is just an open plan kitchen/lounge and a bathroom) so I kinda have everything in here, bedroom, data centre, office, cockpit simulator, recording studio, workshop, exercise area, kitchenette (the shared kitchen is often a biohazard), parts and materials storage... Most normalfags would be dissatisfied with this arrangement but I'm enough of an Autist that I find it comfy. Pic related, it's my work bench. Kitchenette/food storage is to the right (convection microwave, sandwich press, fridge/freezer, water cooler/heater), parts storage shelves to the left, bed is directly behind the camera, server rack is at the foot of the bed, cockpit simulator/desk/recording set up is against the wall on the right. The floor between the workbench and bed is covered in exercise matting. I would be a total NEET if I didn't have a nightshift job and a university course. The air-conditioner is actually for the whole room since it's over 110F for a lot of the summer. I had to nigger-rig all that ventilation shit onto it because it wasn't powerful enough, especially while the computers are running. I also run an air filtration system to keep dust down and an evaporative cooler to add moisture to the air if humidity goes bellow 30%. Extractor fans are fitted to prevent solder fumes from building up in the room. I nigger-rigged a water line out of 1/4 inch PVC tubing, running from under the sink in the bathroom, along the skirting board in the hallway, under my door, to a faucet on my workbench. I run a 0.1 micron filter to provide clean water for my experiments, drinking water to my water cooler/heater/ice maker. I'm working on a drainage system at the moment, since currently I just have a 2.5 gallon basin under the faucet that I have to empty manually.
