Will it boot if you set it up as it came delivered to you, hard disk and all?

It did once when I started. 2nd and 3rd attempts were grey screens. 4th and beyond , all black screrns with no chimes.

It's not uncommon for capacitors to *look* pristine when they are in fact completely shot. I can't say for sure whether this is your problem, but capacitors have to get really far gone before a visual inspection will turn up anything. Unless you have an ESR meter, the easiest thing to do is just replace them.

Looks like im going to be doing that. Looking at mouser.com for a set of nichicons.
