Is it to hook up hardware that the standard Raspberry Pi doesn't support out of the box (ie: SATA, m.2, PCI-E)? If so, you could look at some carrier boards for the Raspberry Pi 4 Compute Module, which might grant you more flexibility while still being in the Pi ecosystem. For example, I'm waiting after the Wiretrustee SATA board (https://www.crowdsupply.com/wiretrustee/wiretrustee-sata https://www.crowdsupply.com/wiretrustee/wiretrustee-sata) to make a compact Pi-based NAS.
