Pi uses a standard power supply. You can put a Pi in a case. In fact, it's hard to find one on Amazon without a case. Of course you can develop on it. That's the whole point. Pi 4 has pci-express, no?

I struggled with a power supply for the pi all the way up to the pi 4 - always getting the low power indicator. I struggled with the pi SD card - extremely slow and always the possibility of corruption. I struggled with pi graphics - none of my projects every had accelerated graphics, not even blits. I struggled with pi USB - at first it was power and speed, now it might be in better shape but not all the way there. The pi is still limited to ~ 15w. When you get to the pc ecosystem, and it's really just a bit more expensive, you get a step up in capabilities. You get all the voltages. You can get a 300w or a 1500w power supply. You can add a graphics card. You can put it in a case that has room for more than just the board. Say, I/O? I wish the pi had a nice metal case that had a 2x the width allowing for an enclosed breadboard or the like. Or a case with all the connectors on one side. > Pi 4 has pci-express, no? really? where is the slot? (I said not compute) ;) btw, I'm not anti-pi, the opposite in fact. Maybe I could say it in another way -- what if you could have an itx form-factor pi? I think that would be very exciting.

> Pi 4 has pci-express, no? Not the pi, but the vaguely-similar (better, IMHO) https://www.pine64.org/rockpro64/ https://www.pine64.org/rockpro64/ has a 4x pcie. Works great for a sata/raid controller, but still has plenty of "embedded" limitations - you can't just plug a graphics card into it.

  What's preventing you from using an AMD graphics card, assuming it could be fully inited via modesetting DRM and AGESA?

    Hmm I always assumed that there were missing/unsolved pieces of the driver that would need to be fixed first, based on the way that support for these devices seems to need to be solved one by one [0] but it looks like at least someone has made progress on a different board [1] [0] ayufan https://docs.google.com/spreadsheets/d/1pCqJg0VSzvihUOoxCOq3wt5JeGB4iApAyBBfc_BGv2A/ https://docs.google.com/spreadsheets/d/1pCqJg0VSzvihUOoxCOq3...

    Last I saw the chipset can't map enough memory space to PCIe for GPUs to work, but this might be possible to change with a firmware update.
