The Raspberry Pi is a wonderful platform for DIY projects. You are going to need a decent case if you plan to use it like a regular computer. The MACSBOOST Carbon Fiber & Billet Aluminum Raspberry Pi Case is worth a look. It not only looks cool but also promotes proper heat transfer.
The case has a stainless steel power switch with a blue ring LED indicator light. Simply bring your Pi unit, and you are ready to go.
