Inside the barebone system resides a socket 478 mainboard for Pentium 4 processors featuring two DDR memory slots. Shuttle has opted to omit the AGP slot for add-in graphics cards, somewhat limiting this system's upgrade options. Before installing the additional components, the XPC has to be disassembled completely. Luckily, this task is quickly achieved and not at all complicated.
