I was reading PC gaming news and saw an article about using a cardboard box for a case. I said, "What the heck, why not?" And promptly grabbed a box. I dissembled my torture PC, a ten year old HP OEM I use to mess around with without needing to worry about breaking crap. Everything is entirely held together with zip ties. No screws were used in this build. It's running Windows 10 Home, and can't run Minecraft. What is the point of this build? I do not know. This is probably very flammable, and I wouldn't advise using one of these indoors, especially with a 10 year old dust clogged PSU. Cheers!
