AOpen AK79D-400 Max nForce 2 Motherboard (cont.)Description:
AOpen used a black pearl PCB for the AK79D-400 Max which looks very sophisticated. It makes the various color coated connectors stand out even more.
The CPU socket is located at the top of the board, about a third to the left. It is oriented with the locking teeth at the top and bottom. On the left and right side of the CPU socket are mounting holes for waterblocks or heatsinks that use this kind of setup.
Just below the CPU socket is the Northbridge. It is covered with an aluminum heatsink that is latched on and has AOpen painted on it. The pictures on the box and in the Easy Installation Guide all show a small fan on the Northbridge heatsink, but one was not found on the actual motherboard.
The three memory slots are located a third to the right. The two outer slots are colored blue and the middle slot colored light purple. The Southbridge, located below the memory slots, is covered with a small aluminum heatsink that is glued on. The ATX power connector is colored red and located to the right of the memory slots.
The Floppy and IDE connectors are located on the far right side of the board and run parallel with the length of the board. This is a pretty good location because it helps to keep the ATA ribbons/cables away from the rest of the board and closer to the drives. The floppy and first IDE connector are colored black. The second IDE is colored blue. A third IDE connector is located towards the bottom of the board and it runs perpendicular to the other two IDE connectors. This IDE is used by the Promise Serial ATA controller located above it. The Promise controller also controls the two Serial ATA connectors next to it.
Each expansion slot is colored according to type. The AGP slot is blue with a white locking mechanism. Five PCI slots are colored peach and the ACR slot is colored orange. In my opinion, the ACR slot is a ridicules concept; it is just a PCI slot going the other way, and so far I have yet to see an ACR expansion card.
The bottom of the motherboard consists of a row of connectors from the front panel, to the IrDA, to the game port connectors. The front panel connectors are color coated and properly labeled, making it extremely easy to connect the power, reset, HDD lights and buttons' pitches.
The I/O ports consist of the standard assortments. Four of the six USB 2.0 ports are present; the other two are left as headers on motherboard.
One of the included expansion brackets consists of two USB ports and a midi game port. Another expansion bracket consists of two IEEE1394 ports. A third expansion bracket consists of coaxial and optical S/PDIF in and out ports.
