Try as I might, I could not find a new motherboard that would fit in this case and meet my peripheral requirements.  I really love this case and this old socket 939 mobo is plenty powerful for an HD MythTV front/backend.  In fact, I'd swear that Silverstone designed this case around this motherboard.  Every cable is the perfect length, every conceivable feature on the motherboard can be used in it's most ideal way.  I was really bummed when it failed.  Luckily, a re-cap is all it needed.  It works!
