I would highly recommend avoiding the J series processors. I’ve had nothing but issues with them with QSV. They are also not socketed, and therefore non-upgradable. 4GB of RAM is also below my minimum recommendation of 6 or 8GB.
Yeah - looking at the layout of these it seems unlike the HP S01 that the PCI-E slot might actually support a 2 slot GPU. I’d like to throw an A310 in there to enable AV1 encode and transcode. I’d hope the stock PSU could handle that. Not sure if I could get away with an A380
