I built this PC about ten years ago while I was in high school, and I'm hoping to upgrade it so my partner and I can play newer games together. I'm also running into hardware limitations and frequent driver problems. Before buying parts, I'd like to know whether anything from the current build—such as the case, storage, motherboard, RAM, cooler, CPU, or graphics card—is still worth keeping, or whether I should plan for a nearly complete rebuild. The full parts list is available through the linked build list.

The case and possibly the storage are the main parts worth reusing, assuming the case has decent airflow and the drives are still healthy. For modern gaming, the CPU, motherboard, RAM, and graphics card are likely too old to upgrade individually in a worthwhile way. Replacing the platform as a group will give you better compatibility and avoid chasing problems caused by aging hardware.
The cooler could potentially be reused if you can get a compatible mounting bracket for the new CPU socket, but that usually isn’t guaranteed after a decade. The RAM is also unlikely to carry over if the new system uses a newer memory standard. Keeping those parts would save relatively little compared with the reliability and performance benefits of replacing them.
I’d treat this as a new build rather than just installing a newer graphics card. An old CPU and motherboard can bottleneck a current GPU, older RAM may not be compatible with modern boards, and the power supply may not have the right capacity or connectors. You might be able to keep the case and reuse a secondary storage drive, but check the drive’s health and make sure the case supports the new components.
