No major manufacturer builds computers with AGP slots.
There are currently no pre-built computers offered by major manufacturers that still use AGP slots. Instead, they have all transitioned over to AGP's replacement, PCI. This means that if you need a computer with an AGP slot, you have two options: You can either choose a used or refurbished computer, or you can custom-build your own using one of the available AGP slot motherboards still available on the market (see Resources).
Disney Dream Desktop Computer
While this computer is no longer being manufactured, it may be possible to find one on the used or refurbished market. The computer offers your younger children a Disney experience with bright colors and Mickey-shaped ears on the monitor. The computer comes equipped with an ATI Radeon 9100 graphics card, but that can be swapped out for any AGP 8x (or less) graphics card.
Dell Optiplex GX270
This computer, like others manufactured by Dell with AGP slots, is no longer available as a new computer. However, the computer is regularly featured on a variety of recycled and rebuilt computer web sites. The computer also comes equipped with Dell's management software, which allows you to track the health of your computer. It can accommodate any AGP graphics card, as long as it is a half-height card since the chassis cannot accommodate a full-height AGP card.
Emachines T2200
Like the other machines in this roundup, the Emachines T2200 is longer being manufactured. However, it often turns up for sale on second-hand computer sites and is a mid-weight contender for an AGP graphics-based computer. Featuring an AMD 1.8Ghz processor, it is not super-fast. However, it handles Windows XP well and should be able to run Windows 7 as well. As originally equipped, the computer also comes with a 100GB hard drive and 512MB of RAM (meaning you will have to upgrade for Windows 7 since it needs at least 1GB of RAM available).
