Lenovo Legion Go Mod Transforms Handheld PC into a Portable Arcade Machine

Handheld gaming has exploded in recent years, with countless devices popping up to tempt gamers on the go. Most of these portables borrow ideas from the Nintendo Switch, but only a select few, like the Lenovo Legion Go, dare to try something truly modular. Unlike their console cousins, these PC-based machines are a playground for tinkerers, offering more freedom to swap, tweak, and upgrade to your heart’s content.

What if that modular design could go even further? Imagine a handheld gaming PC you could snap apart and rebuild to fit your favorite play style. That’s exactly the spirit behind a recent DIY project that reimagines the Legion Go as a portable arcade machine. It’s a wild experiment that took plenty of late-night trial and error, but the end result is something any retro or arcade fan would love to get their hands on.

Most people picture arcade controls as chunky joysticks and big colorful buttons. But leverless “all-button” layouts are taking over the fighting game scene for their precision and speed. With every button lying flat, it becomes possible to create a slim, folding device that’s both compact and satisfyingly tactile. This opens the door to a clamshell design, one you can fold up and toss in your bag, just like a mini laptop.

Enter the Lenovo Legion Clam, a mod that swaps out the Legion Go’s controllers for a custom, 3D-printed shell packed with arcade-style buttons. The entire project feels like a celebration of DIY energy, from the homemade circuit boards to the use of genuine laptop hinges for that satisfying open-and-close motion. And when you’re done, the whole thing folds shut for easy transport. It’s quirky, bold, and undeniably fun.

Of course, as with any one-off invention, there are a few bumps along the way. The controller connects via a rather conspicuous USB-C cable that runs along the outside, and the hinge doesn’t let the shell close completely flat. Swapping back to the original Legion Go mode isn’t quick either, since the modded shell is screwed on tightly. For anyone who loves to jump between handheld and arcade styles, that’s a bit of a hurdle.

Still, the payoff is hard to ignore. The experience of playing platformers or fighting games on a custom, leverless arcade pad is so enjoyable that it’s easy to forgive a few rough edges. It’s a glimpse of what handheld gaming could be if manufacturers leaned into modularity, making it easy to transform a single device into whatever the moment demands. The dream of a truly flexible portable system suddenly doesn’t seem so far-fetched.
