The SER5 Pro's six-core AMD Ryzen 5 5500U drives three simultaneous monitors through HDMI, DisplayPort and USB-C, well ahead of the G3 Pro's HDMI 1.4-only dual output capped at a low refresh rate for 4K. The G3 Pro's one edge is a slightly larger drive, 512GB against 480GB, plus a second free M.2 SATA bay that lets a buyer add capacity later, something the SER5 Pro's single M.2 slot does not offer. Both ship with 16GB of dual-channel DDR4 that maxes out at 64GB, 2.5G Ethernet and Windows 11 Pro, so memory headroom is a wash between them. Buyers who want a triple-monitor desktop with a lower price and a strong owner track record should choose the Beelink SER5 Pro (16GB + 480GB), while anyone who wants a second free storage bay for future expansion should pick the GMKtec NucBox G3 Pro (16GB + 512GB).
