Of all the big tech developments of 2025, perhaps none have been more surprising than the rise of the mini PC from niche hobbyist fave or low-powered conversation piece to legitimately fast, powerful desktop replacements at competitive prices. The mini PC has emerged as a real force capable of creative workloads, multitasking, and even gaming, all while taking up next to no space on your desk — or even no space at all when you mount it behind a monitor.
Two of KAMRUI’s best and most popular mini PCs — the AM21 and the Hyper H2 Mini Gaming PC — are also two of Amazon’s best tech deals as we head down the homestretch of the holiday shopping season. The Ryzen 7-powered AM21 is marked down from $700 to $500, and with the code KAMRUI874501 you can drop that even further to just $475. And the Intel Core i7 Hyper H2 is the perfect deal for gamers with this limited-time 38% off deal that drops its price from $820 to just $510.
If you’ve been waiting for a compact system that doesn’t require compromising on performance, the KAMRUI AM21 is the model to pay attention to. It’s powered by the AMD Ryzen 7 8745HS, a “Zen 4” 8-core, 16-thread processor capable of a blistering 4.9GHz in speed. This chip, from is designed for modern creative workloads — photo and video editing, multitasking across dozens of browser tabs, streaming, coding, and more. It’s the kind of CPU that used to only appear in premium laptops or small-form-factor desktops, but here it’s paired with a compact chassis you can hide behind a monitor with the included VESA mount.
KAMRUI sweetens things with Radeon 780M integrated graphics, enough for design work and streaming, 32GB of fast DDR5 RAM, and a 1TB NVMe SSD — both impressive for a machine in this price bracket. With the extra slots inside the AM21, you can expand the RAM to 96GB and the storage to 4TB. With this kind of power, applications launch fast, large files move quickly, and the system stays smooth even when you’re juggling tasks. If you’re someone who bounces between creative tools and productivity apps, this kind of overhead is invaluable.
On the connectivity side, the AM21 is stacked. You get USB4, multiple USB-A ports, HDMI outputs with 4K support, dual LAN, Wi-Fi 6, and Bluetooth. That allows up to four external monitors at 4K resolution, fast external storage, or docking-station-style connectivity without clutter.
In practice, the AM21 is a tiny workstation: compact enough for a living room, fast enough for real work, and flexible enough to act as a daily driver for creators, professionals, or anyone who wants laptop-level performance in a desk-friendly form factor.

The Hyper H2 occupies a different lane. This is the ideal mini PC for everyday computing, home-office productivity, streaming, and — yes — gaming. Its compact size, low noise, and modest power requirements make it a great pick for users who want a 10-core Intel processor that can hit 4.9GHz on the speedometer and be a significant upgrade from an oversized tower or an aging or midrange laptop.
The integrated Intel UHD graphics for 13th Gen processors with 64 EUs rips at up to 1.5GHz, ideal for gaming and streaming. The 32GB RAM is expandable to 64GB and the 1TB storage can go as high as 4TB, so you’re never going to be wanting for space or processing bandwidth. Wi-Fi 6 and Bluetooth 5.2, and the option of connecting via the 2.5GbE LAN port — 2.5x faster than Gig ethernet — mean amazingly fast, low-latency connections for online gaming or any other online task.
The Hyper H2 is also a strong contender as a dedicated streaming box: silent, unobtrusive, capable of handling 4K playback across various media apps, and easily hidden behind a big screen with a VESA mount. With enough power and connectivity to power up to three 4K monitors, you can easily game on one, stream on another, and work on a third, if you’re a truly ambitious multitasker.
For small business setups, digital signage, or “grab-and-go” PC needs, the Hyper H2 works as a dependable machine with minimal setup fuss. And like the AM21, it’s built with enough ports and connectivity options to avoid the typical downsides of budget mini PCs. You can plug in peripherals, run dual displays, and use modern wireless accessories without any performance bottlenecks.
This kind of impressive spec sheet and graphics-heavy power is how the KAMRUI Hyper H2 earned the nickname “the Little Steel Cannon.” While this 38%-off Amazon deal is running, maybe it should be called the Little Steal Cannon, because it’s an awesome array of power in a tiny package at a terrific price.
