The small form-factor system provides one expansion slot for a low-profile, 32-bit, 33-megahertz (MHz) Peripheral Component Interconnect (PCI)
card.
The small mini-tower system provides four expansion slots for 32-bit, 33-MHz PCI cards.
Both the small form-factor and small mini-tower systems also provide a slot for one 32-bit accelerated graphics port (AGP) card (low-profile in the
small form-factor system). The expansion slot supports AGP 4x or 2x modes operating at 1.5 volts (V) or 3.3 V. This slot may also be used for a 4-
megabyte (MB) graphics performance accelerator (GPA, formerly called an AIMM).
