"So I've might be committed a tech crime

Two crimes actually

First is a motherboard screwed under the desk without any case, and a custom made support system for a 3070, all of which is powered by a power supply on a windowsill

Second crime is a raspberry pie touch monitor on a hydraulic bracket, but since minimal weight for this bracket is 3kg (or it will extend itself), I've strapped a 2kg training sandbag to it"
