Also, just in case you need to know what brainbox you have. That's an AVP 3.0 model 660 brainbox. Best model you can get for AVP 3.0 in my opinion.
But the 660 model brainboxes have no on-board video. So they must always have the add on PCIe video card installed. Which is the best video possible for AVP 3.0 machines.
Other model brainboxes with the same power connectors on them have on-board video, one VGA for the primary touchscreen and a DVI port for the top display, and don't have the add on PCIe video card. (But they can)
I've setup a lot of AVP machines and have four myself, two are MLD screen machines. And in my own testing, I've found all AVP machines actually work just fine with brainboxes using the on-board video. For machines with MLD screens, many MLD games list that they must have the add on E4690 video card. However, I've tested MLD machines using a brainbox with just on-board video, and it would seem even MLD machines run just fine with on-board video, and I was never blocked from installing/running MLD games for not having the add on PCIe card. And there was no noticable difference in video quality. I just prefer the 660 that has the card because there's nothing higher to upgrade to on AVP 3.0 machines.
However other brainboxes which have on-board video ports, still have the PCIe slot on them for the add on video card so it can be "upgraded". And the same model E4690 PCIe video card can be plugged in as well, making them pretty much the same as a 660. But since they also have the on-board video hardware present, unlike the 660 box, they "can" function without the add on PCIe card installed. With the PCIe card installed on a brainbox with on-board video ports, it simply disables the on-board video in favor of the more powerful PCIe video card when it's present. I'm sure opinions will vary on having the PCIe video card or not on different machines. That's just been my observation.
