A rack unit (RU) is 19" wide and just under 2" in height. a 1RU server is therefore ~2" tall 19" wide, a 2RU is just under 4" tall 19" wide, etc.

If you want to install many full-sized add-on cards, such as extra PCI drive controllers or NICs, you want a 4RU chassis. The 1RU and 2RU chassis require a 90 adapter to mount cards parallel with the motherboard, and limit you to one or three PCI cards.
