This huge model of an Imperial Star Destroyer houses a gaming PC.
Modder Sander van der Velden built the model and used the PC components as various ship parts such as the engine. The frame was constructed using aluminium cuts, while everything else passed through a 3D printer.
It's big and impractical but then, the Dark Side always did have a flair for the dramatic. At least if it crashes you know you can always blame the Rebel scum.
There's a few images of the model below and plenty more on the build log.
