eleUniverse Orange Pi Zero 3 Case, N502 Metal Case with 5V 3010 Cooling Fan and 2pcs Aluminum Heatsinks

fit my orange pi zero 3 perfectly with no issues and easy access to the ports.

Edit: Support informed me that this was a rare manufacturing defect. Dunno what happened here, but this case doesn't appear to support the Orange Pi Zero 3. Rare photos of the side of the case with the SD card slot (both on Amazon and the Web) show the slot on the opposite side, compared to my photo. Package was also missing heatsinks. Return process started. Such a shame, because the case seems ruggedly-built.

Very simple to install once you look at the pictures in the listing, as the standoffs are a little counter intuitive, or were to me being a PC builder. Heatsinks work great and SoC never goes over 50c until it's under heavy load. Sleek little box that hides well with the rest of my networking equipment!

Solid metal case. Unfortunately, the cutouts for the ports and memory card are slightly misaligned making this case annoying to use. I wouldn’t buy a second one.

I used my Zero 3 for a few days before the case arrived and the Zero 3 stayed around 118degF with no real load. I put the unit in the case and the temps went down to 92degF, with the heatsinks. Definitely worth it for that. Looks smaller than you think but it fits so well. You can get GPIO wires out the side where the 26 pin header is, there's a gap in the side there, as it were. SD Card is kinda hard to remove with the case on but shouldn't be a problem with a pair of needle nose pliers. No space issues with the other connectors either, but I don't have a microHDMI to test that one. You can use your included antenna or get a uFL to SMA cable and upgrade from the included antenna.
