Shuttle XH110G packs a PCIe x16 slot into a three-liter package
 

The prioritization of power efficiency in CPU design has led to an era where machines displacing as little as two liters can deliver an enjoyable gaming experience at a resolution of 1920x1080. Typically, shoehorning gaming chops into a small chassis requires trade-offs like non-upgradeable components and limited CPU support. Shuttle's XH110G barebones system takes a different route. This little beastie offers support for desktop LGA 1151 CPUs along with a PCIe x16 slot ready to take in an expansion card.
