Take note that not all motherboard manufacturers need to support all the available interface options like DisplayPort (DP), the 4 x1 PCI-E 2.0 slots, 5 PCI slots, etc.
In the case of mATX motherboard iterations you are not likely to find the 5 PCI slots or even 4 x1 PCI-E slots.
Our sample GeForce 9300 board from ECS did not have a DVI or DisplayPort video out and it only had 2 x1 PCI-E and 3 PCI slots.
It’s a pretty clean layout, I wonder why they didn’t put two PCI-Express x16 slots on this baby?
The momentary switches for Power On and Reset are visible at the top right hand of th above picture. Strangely ECS did not include a SMD LED for power or drive activity. They can be forgiven for not including a piezo-electric speaker.
