2026 verdict
A compact, all-aluminium desktop against a bare-bones box: the Geekom A5 Pro (Ryzen 5 16GB + 512GB) rates higher with owners, carries a longer warranty, and doubles both the memory and the storage of the GMKtec NucBox G3S (8GB + 256GB), at 16GB and 512GB against 8GB and 256GB. The AMD Ryzen 5 7430U inside runs at a 28W envelope in a 0.47 liter aluminium shell, which owners describe as quiet enough for a desk and small enough to sit in the open rather than tucked under it, with six USB ports and quad display support through dual HDMI and two USB-C outputs. The GMKtec NucBox G3S (8GB + 256GB) trades that build quality and configuration for a much lower price, running a four-core Intel N95 in a plastic chassis that still covers browsing, office work and dual 4K output. Both memory types are DDR4 and both can be upgraded later. Buyers who want a quieter, better-built machine with more headroom should choose the Geekom A5 Pro (Ryzen 5 16GB + 512GB); buyers on the tightest budget should choose the GMKtec NucBox G3S (8GB + 256GB).
