KKSB Rock 5B Case with Heatsink - Black Aluminum Case

I've got 3 of these and they are fantastic little cases. Cooling seems to work quite well either using the provided passive heat sinks (with thermal pads or paste) or with an active fan solution on one of the systems.

I'm doing an R&D project for work and I needed to get a few SBCs with PoE hats, cases (ideally with Key-Hole mounts), etc. to be able to test a product as well as feasibility to deploy.Sturdiness - 5-Star. I had some concerns when I was disassembling it to get the heatsink and bag of hardware from inside the case, it felt flimsy, but once I put the top grill on and screwed it in, it is plenty solid/rigid.Space - 5-Star. For my purposes, I didn't utilize the passive heatsink as I needed to be able to fit a PoE hat. This case fit the SBC, a 40mm X 40mm X 5mm heatsink and the official PoE hat while also being able to put the lid on and screw it in. Having a couple of threaded holes on the lid for a camera or other mount point is great as well for those of you that need that expansion capability.Customizability 3-Star. While I don't need to customize this for my purposes, the ability to expand on this is limited to 4 punch-outs for small cables and/or antenna for a WiFi card, and the threaded hole on the lid for mounting a camera or other feature to.... That's it. If you don't need flexibility for your project (external access to GPIO pins, etc), then this isn't a consideration for you either, but if you're just looking to tinker and play, this case won't be great for that.Fit and Finish 5-Star. This board came without blemish, the stand-offs align perfectly with the holes in the board, the cut-outs for the I/O ports fit perfectly with no slop or tight fits.All things considered, I'd highly recommend this case for both home-labs and work-place SBCs alike.

Great Case for Rock-5B. The official case may keep the board slightly cooler but was hard to open. This case is much easier to open without risking damage to the board. The mat black paint looks good. The steel plates have a good finish and match against edges very neatly.
