It's just an operating system when it comes down to it. Once mac had crossed over to PC hardware (intel processors) then the difference between the two just came down to looks and the operating system.
Except with building your own mac, you can select quality components that in themselves have lifetime warranties and if something goes wrong then you'll be able to just go down to the local pc shop and get a replacement. Its not recommended for anyone who doesn't know anything about hardware and can diagnose problems. The only two hardware faults I get all the time from friends and family are either a harddrive failure or a faulty power supply. Everything else rarely breaks down if you get quality components.
