Comments
I picked up the GMKtec NucBox M3 for my home office, and it’s been a solid little beast. The i5-12450H handles multitasking and light editing without breaking a sweat, and triple display support is a game-changer for productivity. Love the 2.5G Ethernet and Wi-Fi 6 for fast transfers. Only gripe: USB-C doesn’t charge the device. But for the price, this mini PC is a steal.
