What can I reasonably upgrade?

I've had my PC for a few years, and I wanted to upgrade. However, I know GPUs, RAM and SSDs are wildly overpriced currently, so I feel like the only thing I can really get is maybe a new mobo, CPU, and possibly a cooling fan. This is the system that I currently have:

Mobo: Rog Strix X570E Gaming Wifi 2

CPU: Ryzen 7 5800X 8 Core

RAM: 32Gb 3600 DDR4 (2x16)

SSD: 2 TB; 1TB

GPU: GeForce RTX 3070 8Gb

Cooler: NZXT Kraken X73 (I think)

I don't really have a budget necessarily, but I'm not trying to drop like $1,000.00 on a GPU or some RAM. I was thinking maybe I could find a compatible mobo/cpu for all of the other parts I have? It may not be worth it to even upgrade anything at this point, but I really wanted to upgrade something--maybe even a new case or something. Thanks for any advice. I'm in the U.S. and the currency is USD.
