Upon opening the box I immediately noticed that the board had an attractive dark red PCB. Although you won't really see the PCB unless you have some sort of case window, it is still a welcome change from the regular light brown or green PCBs we are used to seeing. The 4VPX266A features 3 DDR DIMM slots, 5 PCI slots, 1 AGP4x slot and an ACR slot. The P4X266 chipset supports 3.3v AGP2x devices however, the ACorp 4VPX266A only supports 1.5v AGP4x devices. This means that you will not be able to use a 3.3v AGP2x device, such as the 3dfx Voodoo 5 if you decide to purchase the 4VPX266A. ACorp decided to include an onboard VIA 10/100 ethernet controller on the 4VPX266A instead of onboard sound.

Unlike the AV40, The 4VPX266A's FDD header is well placed. However, its ATX connector is in a position that requires you to run the power cable over the top of the heatsink/fan unit, restricting airflow. The 4VPX266A's North Bridge is cooled by a green colored, passive heatsink. Although not as robust as the AV40's North Bridge cooling solution, the passive heatsink was more than sufficient.
