So I have a old Compaq presario lying around, And I was wondering if I could build a relatively high end PC into that like a sleeper car.
A sleeper is a car that has high performance and an unassuming exterior. Sleeper cars are termed such because their exterior looks little or no different from a standard or economy-class car. In some cases the car appears worse due to seeming neglect on the owner's part, typically referred to as "all go and no show". While appearing to be a standard or neglected car, internally they are modified to perform at higher performance levels.
