Gaming PC - RTX 2080Ti, Intel Core i9-10850K

My friend upgraded to a new PC and I'm helping him sell his old one. He built this PC on his own around 3-4 years ago. Would highly recommend someone with computer knowledge to buy this as the PC case probably needs replacing. My friend didn't know how much space he needed when he built it years ago. And so the PC can get the room hot when gaming, as the AIO cooler fans couldn't fit inside the case, so he put them outside. But the PC does fully function as is, albeit temps and airflow can be improved is all. Selling the 2080Ti on its own for $400 if nobody is interested in the rest of the PC. My friend is open to offers but not right away, as he wants to try to get the most he can for what he spent on it. If you are interested in any other part or have questions about the PC, let me know.
