The Marvell 88SE9128 PCIe x1 to 2 SATA 6 Gb/s ports RAID controller is located near the P55 chipset:



Near the ATX 24-pin power header, we can find another fan header:



In the top right corner of the board, we can find an auxiliary power connector for graphics card along with another fan header:



The memory slots’ channels are color coded differently, so we can identify them much easier:



Near the chipset, we can find a PLX PEX 8608 PCIe Gen 2 switch covered with a passive heatsink which offers 8 PCI Express Gen2 (5.0GT/s) lanes:



The SuperIO chip along with the clock generator can be found between the two first PCI-Express x16 slots:



The cooling system is composed from multiple heatsinks linked together with heatpipes; each of them has similar artwork and between the VRM heatsinks and the NF2100, we have dual heatpipes traveling between them:



Between the VRMs and the heatsinks, we can find blue thermal pads:



The 8-pin ATX power header can be found near the two VRM heatsinks:



The board does also come with the following connectors and buttons:

1 x PS/2 keyboard/mouse combo port

1 x CLR_CMOS button

2 x eSATA 6.0Gb/s ports
