This open-air chassis PC is unlike anything you’ve ever seen

If you’re a fan of unusual PC builds, you might like this new release from Nagao Seisakusho, a Japanese open-frame chassis specialist. Instead of locking all the components into the chassis, Nagao releases them — and this time, the company has spiced up the build with an unexpected detail.

Nagao just unveiled a monitor mounting bracket to match the outdoor chassis, allowing customers to build a fully portable all-in-one PC themselves.


Nagao is a brand that makes open-air chassis for all kinds of motherboards and usage scenarios, including standard ATX, Micro-ATX and Mini-ATX motherboards. The company has several options up its sleeve that allow users to customize its PCs beyond what a typical chassis usually allows.

Spotted for the first time by @momomo_us on TwitterAlso known as the ‘N-Frame PC Chassis’, these ‘open air’ cases allow you to rebuild your PC from scratch in a neat way.

As can be seen from the mounting bracket images, the result is unlike anything else we’ve seen. The photos show the potential of the chassis, with a massive graphics card that is completely unconstrained by the size of the motherboard. The monitor hangs on the side of the chassis, with the motherboard and components behind it. The whole setup is highly upgradeable, easy to check and probably wonderfully easy to clean. (Did you know that you should clean the inside of your PC once every few months?)

Usually the best all-in-one PCs tuck the components away in the screen, just like the beautiful 24-inch Apple iMac. On the other hand, it’s hard to deny that Nagao’s vision certainly scores some points when it comes to uniqueness, and for the actual performance of the PC it is certainly useful. Instead of cramming things into an ultra-dense space, the components get plenty of cooling just by being out in the open.

While Nagao’s products may seem like a lot of fun for an avid PC builder, they aren’t readily available in the US. However, you can check them out on the Japanese version of Amazon if you want to give them a try. A Nagao Open Frame Micro-ATX chassis costs JPY 14,955, which equates to about $112.


Throwing out the chassis when building a new PC certainly has a number of benefits, from an increase in airflow to the fact that it just looks pretty cool. It’s also easier if you worry less about the size of the components, and cable management becomes less of an issue if you have enough space and options to organize them. Plus, maintaining an open-frame PC is pretty easy — after all, it’s all in the open at your fingertips. But builds like Nagao’s aren’t without problems, and seeing a handle on top of the PC — especially with a monitor on it — raises the issue of security.

No doubt Nagao will have tested the hardware before it was ever released. It’s still a little scary to imagine what could happen if the monitor ends up weighing more than the rest of the chassis, which depending on the size of the screen, it’s entirely possible. The monitor mount has 75 x 75 and 100 x 100 VESA mounting holes, which could translate into a fairly large screen.

Once an all-in-one PC is built based on Nagao’s products, the added handle makes it easy to carry anywhere. This, again, might make one a little worried. Just imagine if even a little bit is spilled or your beastly graphics card is accidentally scratched… It’s not likely, but it could happen. If you want to try this out for yourself, you’ll need to weigh the pros and cons and decide how much portability you want to risk with your unique build.
