Andy, got your pm but you have your pm'ing turned off, so I'll post here.
I just moved all of my stuff into a P180 lastnight also. And I did get a chance to take picks of how my XP-120 looks on the motherboard. It was so late lastnight, that I was going to wait til I get out of work today to post them to the forum.
I have the heatpipes facing the capacitors and mine don't touch them. Close but they don't tough them. If you had them facing towards the ram, I believe you'd lose dimm slot 1. But you can have it face either way. Good luck.
I'll post my pics later today.
