September 9, 2026: A previous version of this article provided incorrect attribution for the build, which was created by LarBearLair. The original Reddit thread that took credit for the build and claimed the case cost $1,000 to make has been corrected since publication. PC Gamer apologises for the error.
Have you ever felt like your gaming PC was too stationary for your liking? Too few moving parts? Well, boy, does LarBearLair have a build for you that combines a see-through case with a whole bunch of actual rotating parts.
Fittingly called the "Rotating PC", the build has a spinning fan, GPU, motherboard, and PSU inside a glass case, with four fans at the bottom and four fans at the top to control the temps.
The pole in the centre of the build has an RGB strip around it, illuminating all the hardware. It's a truly ridiculous build, and one I'd assume was purely for show, if the creator hadn't also posted it on builds.gg, a PC building website, to explain the methodology.
They reportedly took four months to build it, and didn't even know if it would work until the third. They claim, "The slip rings are the key to how it can rotate without the cables getting twisted up."
Slip rings tend to be used in machinery to give power to components that need to spin or move. LarBearLair says slip rings "are used everywhere from your ceiling fan, to an MRI machine, to a merry go round, or to a power generating wind turbine."
They also admit that the design is pretty impractical (who could have seen that coming?). They say, "This is a backward and unnecessarily complicated application of slip rings. Normally, only the bare minimum electronics are installed on the rotating part, with the rest being on the stationary base. I've put most of the electronics (the PC) in the rotating chamber, just because I thought it was cool that you could."
Not only is the PC functional, but it has a little switch on the front that can set the motor to spin in slow motion, regular speed, or at "maximum speed".
No, it's not clear if making the motor spin quicker makes the PC run any faster, but it will probably feel a bit more powerful spinning at high speeds.
