A do-it-all desktop PC preloaded with Windows 11 Pro and powered by a big-name processor really shouldn’t be hanging around in the sub-$350 search results. And to be fair, the 4.5-star-rated GMKtec G3 Pro Mini PC normally runs a more typical $460 price. But Amazon’s made the G3 Pro one of their better post-Prime PC deals with a limited-time 30% discount that lowers the price to $320.
The “mini” part of the name lets you know the G3 Pro is roughly the size of a paperback book, a pleasingly compact size that saves you desktop space while still packing a big punch for external connection options. The Intel Core i3-10110U dual-core processor with Hyper-Threading can hit a boost clock speed of 4.1 GHz to tackle web browsing, Office apps, video calls, and everyday multitasking with ease. Provide your own monitor — or two 4K monitors, since the G3 Pro can easily handle both — keyboard, and mouse, and you’re in business.
Dual-Channel Memory
The 16GB DDR4 memory built into the G3 Pro runs in dual-channel configuration, doubling the memory bandwidth compared to single-stick setups. Combined with the 512GB M.2 SATA solid-state storage drive, the G3 Pro loads Windows and applications quickly and handles multiple open browser tabs and productivity apps without the drag that plagues entry-level mini PCs with 8GB of single-channel RAM. A secondary M.2 2280 NVMe PCIe slot is available for storage expansion.
The G3 Pro’s dual HDMI 2.0 ports both support 4K at 60Hz, which means the G3 Pro drives a full two-monitor 4K setup from the integrated GPU without additional hardware. Four USB 3.2 ports running at up to 5Gbps handle peripherals, and the 2.5 Gigabit Ethernet port — powered by the Intel i226 controller — delivers network speeds 2.5 times faster than standard gigabit for anyone running local network transfers, NAS access, or self-hosted services. WiFi 6 with 802.11ax and Bluetooth 5.2 round out a robust suite of wireless connectivity.
Server Potential
The G3 Pro has a server-adjacent feature set that’s well worth noting for IT users. Wake on LAN, PXE Boot, RTC Wake, and Auto Power On make the G3 Pro usable as a lightweight home server or Proxmox node. The 2.5GbE port explicitly supports Linux, Proxmox, Firewall Server, Ubuntu, and ESXi VMware out of the box, just as easily as it runs Windows 11 Pro for non-tech-intensive usage.
During this limited-time Amazon sale, the GMKtec G3 Pro Mini PC delivers 16GB of dual-channel RAM and 512GB of storage included for just $320, easily undercutting most comparable mini PCs at this configuration level. The 30% limited-time discount should push this compact office machine or capable small-footprint desktop to the front of your post-Prime Day shopping list.
