I know I'd grab a refurbished G5 tower if I had the mulah, although it probably limits you to using PATA hard drives externally, as would anything newer from Apple. I do wonder what could cause mysterious little failures in a system like you're describing. It's always terribly annoying when a problem is intermittent and doesn't follow any logical course. And when a system gets old enough, it starts getting tempting not to bother hauling it into a shop. I don't think I've ever done that with one of my own systems, though I've had many a problem occur over the years with various models. Eric W.
