It is no secret that Valve may position the Steam Machine at a higher price than people expect. That is where Kamrui steps in with its custom Mini PC. It comes with a Ryzen 7 8745HS, 32GB of DDR5 RAM, 1TB M.2 NVME SSD, and Radeon 780M graphics.

Listing parts does not always help if you are not sure what they mean, so here is what this compact system can actually do. It is ideal for emulation and handles modern games at respectable frame rates. Expect smooth performance in titles like GTA V, Delta Force, or even Forza Horizon 5.

Is the Kamrui AM21 Mini PC worth it?

There is solid value here, even if you do not use the discount code KAMRUI8701. At $489.99, you get a powerful machine for its size, and you can expect smooth 1080p gaming in many titles. With some settings tweaks, you may be able to push a fair few games even further. If you are into emulation and you ethically source your games, this system should have no trouble acting as a reliable emulation box.

With the current market, the 32 GB of DDR5 RAM could be a reason on its own to consider this Mini PC. Memory prices continue to rise due to heavy demand from AI datacenters, and having this amount at this price is rare. If the AM21 still feels too costly, Kamrui offers a smaller and more affordable option that may suit lighter workloads.

A more affordable option with solid everyday performance, the Kamrui E3B

If the AM21 feels a little too expensive, the KAMRUI E3B is the cheaper alternative that still offers strong performance for everyday use. It comes with the Ryzen 7 5825U, 16 GB of DDR4 memory, and a 512 GB M.2 SSD. It is not built for heavier gaming, but it handles lighter titles, some emulation, browsing, work, and media playback.

The full function Type C port supports charging, data transfer, and 4K display output, which makes it flexible for desk setups. You also get HDMI and DisplayPort, meaning it can run up to three 4K displays at once. WiFi 6 and Bluetooth 5.2 keep it connected, and the small air cooled case stays quiet under normal use.

Usually the Kamrui E3B Mini PC clcoks in at $399.95 but with this discount code KAMRUI5813 you can grab it as cheap as $239.97 on Amazon
