(Image credit: Beautiful-Turnip-353 ) An enthusiast has shared their first designs, melding the disparate worlds of PC DIY with model railroading. Beautiful-Turnip-353 shared a video of a prototype PC build with a small T-gauge train circling atop their chunky GPU. It adds a truly dynamic aspect to the case window view, and we can imagine a tiny stationmaster shouting, “All aboard the PCI Express, we’re going gaming.”

T-gauge model trains are the smallest commonly available to hobbyists. With a track gauge of just 3mm (0.118 inches) and a model scale of somewhere between 1:450 to 1:500, these are the minnows of the model railroading hobby world. Nevertheless, once properly set up, T-gauge builders can enjoy realistic speed controls and the convenience of magnetized track building systems. They also fit well in the smallest of spaces – or allow for the most intricately detailed large-scale dioramas.

Even the biggest and best graphics cards don’t really have enough room for anything more substantial, so T-gauge is the best choice in a PC like this. T-gauge track has a minimum corner radius of approximately 60mm; moving up to Z-gauge would double that. However, perhaps the GeForce 60 series will inadvertently open up Z-gauge options to the model train/PC building enthusiast community.
