Well, apart from the fact that laptops have relatively poor ergonomics and are difficult to repair and upgrade, they are an expensive solution if you don't need portability. Also, most of my audio hardware requires a PCI slot. But the main reason was that I set out to build a completely silent machine, and because of the tightly packed electronics in a laptop a fan is typically required. These are usually very small fans producing a high pitched whine when the CPU is under load, which is exactly the kind of noise I was trying to avoid. Cheers Daniel
