The Raspberry Pi really has captured the imagination of the geek community at large. From being sold out in minutes, to various projects already in the works, and even a 3D-printable case -- everyone wants a slice of Pi. Now if you don’t happen to have a 3D-printer to hand, a couple of entrepreneuring eBayers have come up with a two comical DIY cases you can buy for charity.
While the simple cardboard case is good, I particularly like the Hackney WACKO case. It's multi-functional; has great ventilation to keep your Pi cool; decent impact protection (along certain axises anyway), and is fully recyclable when you're done fiddling with Linux. It's currently up for £10 with all proceeds going to Great Ormond Street Hospital, so you can grab yourself a bargain and do your good deed for the day in one shot. [eBay 1, 2]
