Not slots in the big comp sense but the tech is there and it’s just started to get used for storage devices (e.g. NVMe M.2 ports and built in eMMC modules). Also PCIe-backed network ports (2.5Gb)
If you fancy taking a look then three good SBCs I’d support are:
Rock Pi 4 - best tech support with their own Linux builds
Orange Pi 5
Banana Pi M7 - best for community of weirdos
Always worth checking they get good support (wiki, docs, forums) with recent OS builds. For example Orange Pi isn’t great at providing builds for it’s boards. Banana Pi is great for giving users the chance to ship their builds to others so the Wiki is crammed with newish builds. Rock SBCs have official OS builds
