Though mini-ITX has gotten plenty of love from Zotac and a few other manufacturers, the potential performance of this small form factor has always been limited by power consumption. The highest performance CPUs use more energy, producing more heat waste and requiring more advanced power regulation circuitry. The amount of space and cooling available in a typical mini-ITX system just wasn't enough for the high-end chips like the 130W Core i7's for LGA1366. As a result, power users who wanted mini-ITX PCs had to make due with 95W chips from Intel's budget socket, LGA1156.
