Sleeper Build

A PC with an external case (if desktop) or shell (if laptop) that appears incredibly outdated, but when opened, contains modern parts, and when turned on, runs a modern operating system.

Some guy broke into my house last night, but luckily he never took my PC.
Oh yeah, that's probably because you have a sleeper build.
