The port on the motherboard is 40 pin but accepts an 88441-style male
plug, not directly compatible with common eDP laptop panels I don't
think. And comparing the pinout in the mobo user manual they've used a
variant this standard 40 pin eDP pinout:

but the pin assignment is reversed top-to-bottom. Also as I understand
it eDP doesn't have any standardized way of controlling backlight
brightness there are a couple ways of doing it and one would have to
probe the motherboard port to find out which method is being used it and
then either find a compatible display or implement one's own backlight
control hardware.

That is to say I just want to make sure they really worked to make this
port useless without their bespoke hardware so I don't have to waste any
more time thinking about interesting things one could do with an
internal eDP port if they hadn't done that, thanks!

  Do you have one of these?

Not made in AMERICA!!!
Also water cooling desktop PCs is kind of silly and those fashion of enclosure seem mostly for the kind of people who would buy audiophile stuff and put extreme camber on their car's wheels.
