One of my teachers’ husbands was throwing away an older cyberpowerpc, and the teacher decided to ask me if I wanted it. I got it, and I noticed that it has a Corsair AIO (120mm). It is most likely an older model, and the block is round. The tubing is not sleeved, and is just rubber. There was one problem, which was that I wanted to put it into my computer, which is a x570 phantom gaming ITX mobo with Ryzen 9 3900x. This has lga 115x, while the AIO is am3+. I was wondering where I could find a retention bracket for my motherboard.
