Hey everyone! I'm working on a project where I want to create a really compact computer that fits inside a case for my Bluetooth headphones. Ideally, I'm looking for a single board computer that's about 4.5x2 cm in size. It should have at least a 500 MHz CPU (I'm fine with either x86-64 or ARM), at least 512 MB of RAM, and importantly, an SD card slot for memory. Can anyone recommend something that fits these requirements? Thanks a lot!

Have you considered the Raspberry Pi Zero 2 W? It's a good option, but it's a bit larger at around 6 cm. It has decent specs for a small board, but just keep in mind the size requirement you mentioned.
Just a little note: it’s an SD card slot you need, not SC. Just thought I’d help clarify that!
You might want to check out the RV Nano. It's roughly 22mm x 34mm, which is actually smaller than your specs. It has an SD card slot, plus Wi-Fi and Bluetooth capabilities. There's also a microphone and audio output, along with GPIO and a serial port. It runs on a RISC-V CPU at about 1 GHz, but it does only have 256 MB of RAM. I’ve run pretty substantial applications on it though—like a public library system! If you tell me what you're planning to run, I could possibly help you find a workaround for the RAM size. Just a heads up, though, it might be hard to get in the USA due to import restrictions on the manufacturer.
