“Expansion options on the board are varied and worthy of note. EPoX includes 3 PCI Express X1 slots, a PCI Express X16 slot for the video card and 3 regular PCI slots for backwards compatibility. Few PCI Express devices exist at the moment, aside from video cards. The positioning of the PCI Express X16 slot is not the greatest. The PCI Express X16 slot is directly above the IDE controller ports. This makes airflow a concern of the board. In fact a long video card, like a GEFORCE 6800 Ultra may cause the first IDE port to be covered. Using our standard GEFORCE 6800GT reference board caused the end of the video card to rest against the first IDE cable. The positioning of the PCI Express X1 slots and PCI slots allows for 2 PCI devices and 3 PCI Express devices to be installed, even when a 2-slot video card is installed.”
