I bought this pre-installed version to avoid having to hack, but if it again, I would take a Pi with nothing on it: in fact it has become absurdly simple to install XBMC on a sd card. I advise such Xbian: you have to download an installer on a Mac or PC and takes care to format and prepare the SD card. Then boots the Pi with this card. Much better than paying for an old pre-installed version. Apart from that the kit is easy to assemble, few screws to close the case. No built-in wifi. It crashes when I put my USB key 16G, perhaps for supply issues. The keys to 8G always work well. Discs with external power supply as well.
