Apart from the motherboard, power supply, drives and cables, a few cards, and dust bunnies, things were pretty empty in there. And while we knew that air had to circulate inside the case, the empty spaces inside still seemed a bit large. Notebook computers came along and really confirmed the impression that the inside of typical computers had enough extra space for a game of baseball. sets standards for the PCI bus generally.

An However, as integrated circuit technology collaborative effort by the PCI Special Interest MD2 card is longer than an MD1 card, but not advanced, expansion boards got smaller and Group and companies including IBM and longer than 6.6" (167.64 mm). Both MD1 and fewer. Motherboards shrank and incorporated Intel, the low-profile PCI standard limits the MD2 cards can be no higher than 2.536" (64.41 drive controllers, graphics adapters, sound height of low-profile PCI cards to a maximum mm) and can be as short as 0.945" (24 mm). cards, additional interfaces, and so on. But of 2.5 inches/60 mm —about 60% of the The diagram below compares low-profile PCI along the way, the standard allowance for height of standard PCI cards. card sizes with standard height PCI card sizes. adapter card height remained the same.
