This is a super elegant and practical armor case for Raspberry Pi 4 Model B. It is an upgraded version to support Raspberry Pi 4 Model B /3b+, great!

Frankly speaking, it is not an enclosure or case, it should be called heatsink because the case itself is CNC aluminum and comes with thermal paste/tape to effectively dissipate heat generated from the processor, RAM IC. Furthermore, it is also integrated with two cooling fans (assembled, but not fasten to the case), just connect the power to run it. Not to worry the Wifi Signal is not affected due to case open design.
