Received the GPU (the correct one XD) and the AIO with extra fans as per the deal.
GPU has some coil whine which can be tolerated once the side panels are closed.
Rest was packed well and arrived in good condition.
Did 90 mins burn in on CPU + GPU (furmark no AA + prime95 small FFT) and temps were under 80 for both.
One of the fans is giving issues with RGB (might be the pogo pins or the fan - not sure) but I am not bothered by it. It was not in control of the seller since he shared details photos and videos of working products before asking for payment and everything looked in order.
Seller has also graciously offered to refund for the troublemaker fan but I am not going to accept it, since I had ordered extras anyway and the fan still works well as a fan without RGB, so in the NAS it goes.
