I received my Raspberry Pi on Friday and was very happy with how easy it was to get a basic XBMC setup working. I decided to leave this Pi set up as the HTPC for a while, which meant I needed to build a case for it. I considered building a basic Lego box case, like I've seen plenty of others do, but I wanted something different. I also wanted something that would help the (already diminutive) Pi "disappear," basically I didn't want something that was obviously a computer or a strange box with wires sprouting from all four sides.
As a big Lego fan, I already have a couple Lego displays set up around my TV, most notably for Star Wars and Lord of the Rings, so if I was to "hide" the Pi in Lego it made sense to start with something there.
I found that the Raspberry Pi board's Lego dimensions (7x11 studs) were only slightly larger than the interior of the new Lego Lord of the Rings Weathertop model, but easily smaller than the Lego model's exterior dimensions. I then renovated the Weathertop model to house the Pi, basically completely rebuliding the interior of the model, while trying to preserve as much of the exterior detail as possible.
The result is a great looking Pi case that easily blends in with my Lego display. The Pi is securely held in place so that plugging cables in and out is not a problem, but the finished model is also not obviously a computer either.
oh, and here's the original Lego model that this is based on. http://thelordoftherings.lego.com/en-us ... /9472.aspx
