Digital DEC Multia (Alpha Generation)

The Multia, later re-branded the Universal Desktop Box, was a line of desktop computers introduced by Digital Equipment Corporation on 7 November 1994. The line is notable in that units were offered with either an Alpha AXP or Intel Pentium processor as the CPU, and most hardware other than the backplane and CPU were interchangeable. Both the Alpha and Intel versions were intended to run Windows NT.

The Multia had a compact case that left little room for expansion cards and restricted air flow, which can cause premature hardware failure due to overheating if not properly cared for. Enthusiasts remedy this by placing the Multia vertically instead of horizontally, allowing the heated air to escape via vents at the top, although this still requires preventing the Multia from overheating due to other factors, e.g. environmental.

Alpha, originally known as Alpha AXP, is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC), designed to replace the 32-bit VAX complex instruction set computer (CISC) ISA and its implementations. Alpha was implemented in microprocessors originally developed and fabricated by DEC. These microprocessors were most prominently used in a variety of DEC workstations and servers, which eventually formed the basis for almost all of their mid-to-upper-scale lineup. Several third-party vendors also produced Alpha systems, including PC form factor motherboards.
