You may not have noticed this though.... If you are mounting the 6125 anywhere except the very top of the rack - no problem. However, if you are mounting it right at the very top you will want to know something that the manual isn't clear on. Those pins you mention above - they look like they are threaded and you just screw them into the hinge from the top. But if you look very closely, you'll see that the pins can be screwed into the hinges *from the bottom* until they stick out of the top the right way. You won't get it mounted in the very top of a rack unless you do it that way (depending on your rack of course).
------ As far as I know, there is one pin header on the horizontal circuit board for connection to the controller and one cable on the vertical board that goes to the PSU. The other side of the PSU (rear in the rack) has the mains power cable (cannot be detached). ------ Yep, they are different then. The desktop power supply itself is identical but the metalwork is not. In addition, the power cord is removable on the desktop version. I will have to make "non-standard adjustments" for that :| ------ It is heavy, I estimate between 40 and 50 kilo. Not good for your back, but when you're on your own (unloading the van) ... ------ Tell me about it. After I mounted the 6125 I noticed the blue cover door wouldn't open all the way due to clearance on the left front of the rack. Further scrutiny revealed that $previous_owner mounted the two front vertical rails with a slant. The front vertical rails are flush with the front of the rack at the bottom, but at the top they are back about 1/2 inch. So today I am unracking everything in the rack, adjusting the two front vertical rails, and then re-racking everything. What a major pain. My fault though - I should have noticed this before I got all the way to the top in putting stuff in the rack. J
