I recently bought a (brand new) Gigabyte X570 Aorus Ultra motherboard and I discovered some weird-looking stains (looks like glue residue) and I have been told that it is most probably flux residue.

I contacted Gigabyte support but they were extremely unhelpful and ambiguous. They said that unless I send them the motherboard, they cannot give me any information and I should contact the supplier.
If you are experienced with hardware and motherboards, do you think that this board could indeed be brand new? Most people have said that this does not like it is new, out-of-the-box, while 2 other people have said that this could be brand new. There are scratches on the shiny metal side shown in the pictures and the stains are all over the board but I couldn't photograph them all through the computer case.
Any thoughts from people with experience?
