Compaq Deskpro EP PCs from the late 1990s. The case could be converted between tower (left) and desktop form factors.
The Compaq Deskpro is a line of business-oriented desktop computers manufactured by Compaq, then replaced by the Evo brand in 2001.[1] Models were produced containing microprocessors from the 8086 up to the x86-based Intel Pentium 4.[2] The Deskpro name, in an inverted fashion as "ProDesk", is still in use by HP, which Compaq merged with in 2002.
