Best Compact Pcs With Upgradeable Ram of 2026

The GMKtec NucBox G10 is a compact mini PC that defies its size with an AMD Ryzen 5 3500U processor and Radeon Vega 8 graphics. This little machine is designed for PC gamers, streamers, and content creators who need a space-saving secondary rig or a powerful HTPC. It’s equally at home in a dorm room, a home office, or as part of a multi-display streaming setup.

For gaming, the Ryzen 5 3500U with Vega 8 delivers solid 1080p performance in esports titles like Valorant, Overwatch 2, and CS2, easily hitting 60fps at medium settings. While it won’t run the latest AAA blockbusters at high frame rates, it’s more than capable for casual gaming and retro titles. The 16GB of dual-channel DDR4 RAM ensures smooth multitasking, whether you’re streaming on Twitch, running OBS, or browsing with dozens of tabs open. The 512GB NVMe SSD provides fast load times, and with dual M.2 slots, you can expand storage up to 16TB for a massive game library.

One standout feature is the triple display output via HDMI 2.1, DisplayPort 1.4, and USB-C, all supporting 4K@60Hz. This is a game-changer for streamers who want separate monitors for gameplay, chat, and OBS controls, or for video editors working with high-res timelines. The 2.5GbE LAN port is another highlight, offering ultra-low latency and stable speeds for competitive online gaming and fast file transfers on a local network. Combined with WiFi 5 and Bluetooth 5.2, connectivity is well-rounded for most setups.

Build quality is impressive for a mini PC. The metal chassis feels sturdy, and the silent cooling system keeps fan noise minimal even during extended use – a big plus for quiet gaming environments. The compact footprint (just 3.86 x 1.65 x 4.06 inches) frees up desk space, and the included VESA mount lets you attach it behind a monitor for a clean, cable-managed look. Setup is straightforward: plug in the power, connect displays and peripherals, and Windows 11 Pro is ready to go. Some users may need to install chipset drivers from AMD for optimal stability, but that’s a minor step.

Limitations are few but worth noting. The Vega 8 graphics aren’t meant for high-end gaming, so if you’re a competitive gamer demanding max settings in Cyberpunk 2077, this isn’t your primary rig. Also, the single USB-C port is used for power, meaning you’ll rely on the USB-A ports or a hub for extra peripherals. WiFi 5 instead of WiFi 6 might disappoint some, but the wired 2.5GbE compensates for that. Overall, the NucBox G10 is a fantastic value for anyone seeking a tiny, quiet, and capable PC for light gaming, streaming, or productivity. It’s a practical recommendation for PC gamers building a compact secondary system, streamers needing a dedicated encoding machine, or anyone wanting a versatile HTPC with serious multi-display chops.

The Ryzen 5 3500U with Radeon Vega 8 Graphics (1200 MHz) handles esports titles smoothly at 1080p. Games like Fortnite (Performance Mode), Valorant, and Rocket League run at 60+ fps on medium settings. For older or less demanding titles, the integrated GPU provides playable frame rates. The 16GB dual-channel RAM reduces stutter during multitasking, and the NVMe SSD eliminates loading delays. This mini PC is best for casual gaming, competitive esports, and as a secondary gaming rig for LAN parties or travel. It won't replace a dedicated GPU for AAA games but is a solid performer for its size and price.

The NucBox G10 offers a versatile port selection: 2x USB 3.2 Gen1, 1x USB 2.0, 1x USB-C (full-function with PD/DP/Data), HDMI 2.1, DisplayPort 1.4, and a 2.5GbE RJ45 port. The USB-C port handles power delivery but can also output video (4K@30Hz) or transfer data. For multi-monitor setups, you can use HDMI and DP simultaneously for dual 4K@60Hz, plus the USB-C for a third display. The 2.5GbE LAN is a highlight for low-latency gaming and network-intensive tasks. WiFi 5 and Bluetooth 5.2 provide wireless options, though WiFi 6 would have been a welcome addition.

Despite its small size, the G10 features an efficient cooling system with a quiet fan that stays near-silent during light use and only ramps up under sustained load. In user reviews, the CPU stays around 42°C at 50% load, and the NVMe SSD remains cool at 39°C under 85% load. The low noise profile makes it ideal for quiet gaming rooms, streaming without fan interference, or use in shared offices. The BIOS also allows adjusting fan curves for those who prefer even quieter operation at the cost of higher temperatures.

The KAMRUI E3B Mini PC is a compact desktop built around AMD's Ryzen 5 7430U processor, a 6-core, 12-thread chip based on Zen 3 architecture. This mini gaming PC is designed for PC gamers, casual gamers, streamers, content creators, and anyone who wants a powerful yet space-saving computer for their desk or dorm room. It's especially appealing to those building a gaming setup or home office that demands strong multitasking and 4K display support without taking up much room.

In real-world use, the Ryzen 5 7430U offers snappy responsiveness for web browsing, office work, and video streaming. Its 4.3GHz boost means games like Fortnite, Valorant, and CS2 run smoothly at lower settings, delivering a enjoyable experience for competitive and casual gaming. The 16GB DDR4 RAM and 512GB NVMe SSD keep the system feeling fast, with quick load times and adequate space for several games. For streamers, the triple display support (HDMI, DP, USB-C) lets you easily monitor chat, stream, and game simultaneously.

Build quality is solid – the all-black metal chassis feels durable and helps dissipate heat. The unit stays reasonably cool during extended sessions, though the fan does ramp up under load. Connectivity is strong: USB 3.2 Gen2 Type-C, multiple USB-A ports, gigabit Ethernet, and WiFi 6 provide everything needed for peripheral-heavy setups. The full-function Type-C port is especially handy for fast data transfers or powering a monitor.

Setup is straightforward: connect a keyboard, mouse, and monitor, then power on. The included 65W power adapter is compact, and the whole system weighs just over 3 pounds, making it easy to move between rooms or take to LAN parties. Software-wise, Windows 11 is pre-installed, and drivers update automatically – no complex configuration required.

A realistic limitation is the integrated Vega 7 graphics: while it handles esports and older games well, it's not meant for AAA titles at high settings. Also, the fan can become audible under continuous gaming loads. However, for its size and price point, the KAMRUI E3B offers a compelling balance of performance and compactness.

Overall, this mini PC is an excellent choice for casual gamers, streamers on a budget, or anyone needing a powerful second desktop for productivity and light gaming. It's also great for college students with limited desk space or gamers wanting a clean, clutter-free setup. If your gaming leans toward competitive titles and you value a small footprint, the KAMRUI E3B is worth serious consideration.
