Used 3900xt ryzen 9 processor with x570 motherboard. I have 32 GB of ddr5 memory. It was ram sticks that shipped with iBuyPower snowblind pre built PCs. I have a mono block on the board that unfortunately has a stripped screw from when I took it apart to clean the loop so I'm not able to clean it but it looks pretty clean inside and will function fine if you want. I have the heat sinks for the VRMs so if you want to swap it out you can do that. Also have a wifi card.
