• Motherboard with VGA OB usually less than fee the last few inches without VGA. Typically, smaller MicroATX (mATX). It is aimed at production cost (UF VGA motherboard specific reduction in economy-class UNT low). Consequently, the number of slots (slot for additional components, such as internal modems, internal TV tuners, etc.), also significantly less than the motherboard, not VGA. But there are also brand motherboard with VGA in the past, obstetricians, that the size of "normal" (ATX), although very rarely.
