The board I think is apparently made by Jiye (is this the same as "TOPFEEL"?): https://www.bilibili.com/read/cv33531133/ which seems to have a bad reputation.
I found some Chinese language discussion on it: https://www.chiphell.com/forum.php?mod=viewthread&tid=2611796&extra=page=1&mobile=no
It seems suspiciously cheap: https://detail.tmall.com/item.htm?abbucket=19&id=809163499762. What are the downsides? (The case is not cnc'd)
