Frankenputer n.
1. A mostly-working computer thrown together from the spare parts of several machines out of which the magic smoke had been let. Most shops have a closet full of nonworking machines. When a new machine is needed immediately (for testing, for example) and there is no time (or budget) to requisition a new box, someone (often an intern) is tasked with building a Frankenputer. 2. Also used in referring to a machine that once was a name-brand computer, but has been upgraded long beyond its useful life, to the point at which the nameplate violates truth-in-advertising laws (e.g., a Pentium II-class machine inexplicably living in a case marked "Gateway 486/66").
