Chinese company Maxsun has a PC component branch, Meterstone, that develops devices such as Intel and AMD-based motherboards and graphics cards. Meterstone also focuses on hybrid systems that collect the more significant advantages of a DIY approach but the usefulness of a mobile chipset's graphics capability and power efficiencies.

Twitter leaker HXL (@9550pro) tweeted yesterday of a new motherboard design from company Meterstone and provided a picture. The Meterstone H45 system showcases an Intel 12th Gen Alder Lake processor with two available desktop DIMM memory sections and a complete PCIe Gen4 x16 slot available for graphics processors. "HXL" took this information from the forums on the website Chiphell.
