2026 verdict
An older chip with newer connectivity beats a newer chip with older connectivity here: the Beelink SER5 Pro (16GB + 480GB) holds a higher owner rating and doubles the memory and storage of the GMKtec NucBox G3S (8GB + 256GB), at 16GB and 480GB against 8GB and 256GB. Its six-core Ryzen 5 5500U is a couple of generations behind current mini PCs, yet the machine drives three monitors at once through HDMI, DisplayPort and USB-C together, and pairs 2.5G Ethernet with Bluetooth 5.4, a newer Bluetooth revision than many machines in this price range. The GMKtec NucBox G3S (8GB + 256GB) runs a more recent four-core Intel N95, but is limited to two displays over HDMI only, with Wi-Fi 5 and Gigabit Ethernet. Both carry a one-year warranty and use DDR4 memory that can be upgraded later. Buyers who need triple-monitor support and faster networking should choose the Beelink SER5 Pro (16GB + 480GB); buyers who just need two screens and the lowest price should choose the GMKtec NucBox G3S (8GB + 256GB).
