The Shuttle XPC R4 6100B is based on Intel's H61 Express chipset for second-generation Intel Core processors (LGA1155) and features new, energy-efficient technologies and innovative functions like USB 3.0 for the office and home environment. It can be configured with up to three drives and up to 16 GB of DDR3 memory at the same time. The two digital monitor connectors on the rear can be controlled by the graphics function integrated in the Intel Core processors - without any add-on graphics card required in the PC. However, the PCI-Express X16 slot can be equipped with an optional discrete graphics card. The front panel can be customized by adding individual design motifs for the maximum individuality possible.
