Intel have been talking up BTX here this week, despite the apparent reluctance of the rest of the industry to move to the form factor. BTX is the first major evolution of the PC form factor since 1995, when ATX launched. Unlike ATX, which had a very quick uptake, we are yet to see any systems or cases using it other than prototypes, despite the fact that BTX launched last year and is an open standard. In fact, even Intel's own predictions state that BTX will take until 2007 to even ship in half of new systems. The BTX standard proposes to cut down on the number of fans in a system. With a single 120mm at the front, ducted over the processor, and the PSU fan venting out the back, adequate system temperatures can be maintained. In fact, adding an extra fan to the chassis can degrade performance, due to the way BTX keeps airflow running. BTX not only has a standard for standard tower PCs, but also for mini Shuttle-esque systems, called picoBTX. This means that you'll be able to buy standard SFF components and mix and match them with cases, rather than buying an entire barebones solution. picoBTX motherboards are around 27x20cm - ideal for modding! We're taking to different companies about BTX, to get their opinions on where this new form factor is going. Look for a follow-up article here soon.
