Raspberry Pi 2 case: a comparison of 6 models

Testing Raspberry Pi 2 B enclosures - Gehäuse im Test

So I bought a couple of enclosures for my Raspberry Pi 2 B computers...

Orbital Case - Das runde Gehäuse für den Raspberry Pi - 2. Generation (Dark Black)
17,90€ Would not buy again. This is a complete enclosure, so you cannot connect anything except the back ports. Connecting a power supply is difficult, since only the back ports are accessible. You cannot connect a HDMI cable, so it's only use case is as a ... I don't know. What was I thinking? 

Exclusives High Quality Designer Metall Gehäuse Case für Raspberry Pi+ PLUS und Pi 2 Model B (die neueste Version 2015)
14,99€ Solid metal enclosure, very expensive but nice. Easy to assemble. The metal case is held together with 4 additional screws, so it won't snap open if it falls to the ground.
Exclusives Gehäuse Case für Raspberry Pi Model B + (B Plus) Case und Pi 2 Model B (die neueste Version 2015) -- Three Part Kunststoffgehäuse (Black Sl 9,99€ Plastic box from Raspberry meets Rydges®. Like the metal case, the two plastic parts are fixed with four additional screws. Costs 25% of the Raspberry itself, which is still expensive, but overall well done.
Exclusives Gehäuse Case für Raspberry Pi Model B + (B Plus) Case und Pi 2 Model B (die neueste Version 2015) -- Two Part Kunststoffgehäuse (Black Builder Edition) 9,99€ Another plastic box from Raspberry meets Rydges, this one exposes all connectors to the outside which makes it more suitable for hardware wizards but less resistance to dust entering the enclosure. The two plastic parts snap together and only loosely hold to each other (that is, you can open this case with one hand).

Aukru® NEU 3-in-1 kit Enthält - Raspberry Pi 2 Model B Gehäuse/Case transparent + Netzteil 5V 2000mA Micro usb + 2x Kupfer Kühlkörper Für Raspberry Pi
15,99€ Like the Black Builder case, same openings, but transparent and with a power supply and a screw driver as well as two copper cooling blocks. The screw driver was really useful in assembling all the cases :). Even though it looks exactly like the Black Builder one, this somehow seems more flimsy, and putting the screws in place was more difficult as they tend to get stuck in the plastic.
Eleduino Raspberry Pi 2 Model B and Raspberry Pi Model B+ (B Plus) Metal Gehäuse Case with Cooling Fan Black 18,90€ A black metal case with a cooling fan, but without any instructions on how to assemble this. Looks like you first have to afix the fan, otherwise the Raspberry will block access to the lower pair of screws. But I do not really need the fan, and since I do not know how to connect it to the Raspberry, I skipped on installing it. The case is okay, but if you need a metal case, the 14,99€ version seems better.

Assembly of all cases took only a couple of minutes and was nowhere as difficult as some Amazon reviews suggested. The Raspberry Pi 2 B always fit very well (with the exception of the clear plastic case - it fits well, too, but the screws are not as tight as I would like them to be, so the board may move a little up and down in the case if shaken).

Recommendation: For plastic, use the Black Builder edition of Raspberry meets Rydges. For a metal case, the designer metal case is not bad, but somewhat expensive.
