I have a 5700G in the A10. It's a nice little case. Takes up a console amount of space, and sits under the TV.
I wouldn't really worry about putting a GPU in there. Unless you're on PCIe4 system, and the 5600G will not be, then the low profile 6400/6500 is useless. Low profile Nvidia cards are all pretty expensive, and the low profile A380 isn't all that great (but probably the best option).
As for Jginyue BIOS updates, I would always be installing the latest for AMD systems. Not sure they were very frequent with their older boards, but their latest B650i board has had a reasonable number of updates.
