NZXT has really managed to turn out a timeless design with the H-series of cases, which has them taking the Tesla approach with small updates vs. trying to reinvent themselves with every new enclosure make sense. The H510i is essentially the exact same case as the H500i, but with an updated I/O and a few small updates when it comes to the internal cabling. The two other bigger updates are the newer version of their smart device and simpler 2.5" drive bays. That said, the case still clocks in at a similar price as the H500i initially with a $110 MSRP, so you are bound to see it at around the magical $100 dollar mark. This is good, especially considering today's landscape with all kinds of imposed tariffs.

Just like the previous version, the H510i scores with the steel front that is folded to run along the top as well; the chassis makes a great impression right out of the box. But even in the interior, you will be hard pressed to find any plastic with the exception of the 2.5" hard-drive trays and cable trenches. That said, NZXT could have taken the opportunity to update the 3.5" bay a little to make assembly a bit easier here—with metal rails or trays, for example. Besides that, the USB 3.1 Gen2 Type-C and audio I/O both are great little improvements, but NZXT could have opted to keep two USB 3.0 along with these, as the cable is there.

All these are small elements that should not be deal breakers to anyone considering the fact that you can install liquid cooling easily in the front and their unique smart device with the CAM software is well designed, functional and easy to use. Even though the H510i represents an incremental refresh to the H500i, it is still an excellent chassis thanks to NZXT investing in an excellent foundation and putting up a solid effort.
