looks much better suited for xpenology then then original gen10, i wonder why its not named gen11, it has everything it need to get the new gen label
for people who prefer pictures and text (you can study in the pace you like) there is a more or less 1:1 version of that video

on 1st look if equipped with a G54xx CPU it would be able to use it for hardware transcoding but i guess price point will not be in favor of that model (and with just 4 drive slots, they should have made it 6)
edit: looks like there is a version with G5420 and 8GB (without iLO5 card?) for ~500€ so its 150-200€ more expansive then the old Gen10
on closer look the iLO extension slot looks like a pcie 4x slot but it closer to the edge so to fit in a normal pcie 4x card one would have to remove the slot mounting from the card, hold it in place in other ways and the card would stand out a little at the back, but it looks like as 10G nic and a storage controller would be possible at the same time
also the drives can be separately seen without any raid from esxi (it mode) so it will be good for xpenology without any additional controller
