This incredibly stylish case that converts a Raspberry Pi into a fully featured Linux desktop computer costs £39.99 ($49.99). The Pi Desktop has been developed by Premier Farnell under its element14 technology brand, and is another example of Premier Farnell’s experience in delivering products to market, from research, through to production. It is only available from Farnell element14 and its resellers.. When combined with the Raspberry Pi, the Pi Desktop provides users with all the functionality they would expect from a standard PC, including WiFi, Bluetooth, a real-time clock, an mSATA solid-state drive interface, an optional camera and a power switch (Solid-State Drive and Raspberry Pi Camera purchased separately).
The Pi Desktop can be connected to a display via the HDMI interface. The Pi Desktop supports up to a 1TB hard drive and also has the ability to boot directly from the SSD, which should significantly speed up the system compared to the more usual practice of running a Pi off an SD card. The kit includes the add-on board containing the mSATA interface, intelligent power controller and RTC; the stylish enclosure; a heat sink; a USB Adapter (Micro-Type A); the RTC battery; and all the necessary spacers and screws.
By the way, it is worth mentioning Pi-Top / Pi-TopCeed which also converts Raspberry Pi to desktop and laptop.
