How to Make a Graphics Card Fit in a PC
Graphics cards are one of the computer components that are upgraded most often. For gaming, video editing or graphic arts, a good quality graphics card can be critical. It's important to know what to look for when buying a replacement or upgrade, but not just the performance specifications. The size of the card and the type of interface are as important as the amount of memory and the resolution.

Place the computer on it's side on a flat work surface with the connectors closest to the table top. Remove the screws on the side of the case opposite from the connections. Remove the side panel.

Inspect the available slots for installing the new card. Note whether an AGP, PCI or PCI-E (PCI Express) slot is open for use. AGP slots are brown in color and are the top slot in the series. AGP slots usually have a tab at the front edge to retain the video card, and sit slightly forward of the rest of the slots on the board. PCI slots are white in color, and have two sections, one long and one short. The short side is toward the front of the computer. There is usually more than one PCI slot. PCI-E slots are usually the top or the bottom slot on the motherboard. PCI-E slots are white and similar to PCI slots, and have two sections. The smaller section of the PCI-E slot sits toward the rear of the computer.

Inspect the surrounding area for obstructions such as cables, fans or frame components. Measure the height of the available space from the board. Measure the available space from the rear of the case toward the area forward of the AGP, PCI, or PCI-E interface slot.

Choose a video card that fits the available interface. Measure the height of the card from the mounting area to the top of the circuit board. Measure the card from the rear face plate to the leading edge of the card. Compare to the available space in the case.

5
Move and secure any cables that may be in the way. Ensure that none of the power or interface cables will interfere with the video card's cooling fan if there is one. Ensure that nothing will keep the video card from sitting straight up and down in it's mounting slot. Install the card and close the case.

Tips & Warnings
Some older video cards can be very long, be sure there is enough free space for the forward edge of the card.
Smaller profile computers require half-height video cards. A full height card has a 5 inch high rear mounting plate. Be sure to measure the one you have before purchasing a replacement.
A higher performance video card must stay cool. Be sure the new card is not so big that airflow is restricted around it.
Some high performance video cards have a dedicated power input, be sure your power supply has one available and that it is the right type.
