I've built two. Neither one lasted more than a year before it crapped out. The two I've bought off the shelf lasted 4 years and the latest 6+. I'll just stick with something that has tech support and components that I know won't fry each other, thanks. 
Operator error! Operator error!

Well I hope this one lasts just as long for you, sorry to hear youve had problems. Usually it's the other way around.
