This is the first part of a multi-part guide to putting together an HTCP. My goal was to put together a cheap(~$200), small, quiet, and efficient HTPC. The CPU dictates the rest of the hardware so let's start there.
Intel Atom processors are by far the most commonly used processor in netbooks because they are small, cheap, and don't use a lot of power. Because the HTPC I wanted was going to be sitting under my TV and on a lot, I didn't want a huge, loud, and expensive PC. Naturally, the Intel Atom was at the top of my list, but would it be able to handle media, specifically HD content?
