[rescue] Ultra 60 CPU "shroud" removal help

[vom513]

Hello all,

Just got my first Ultra machine - an Ultra 60.  It is absolutely filthy - but seems to be in good physical shape.

I have been going through the official service manual PDF - and removing various pieces to clean them.

The CPU shroud has defeated me so far though.

I removed the PSU, 2 sticks of RAM closest to the shroud.  I took out the shroud fan, and the CPUs themselves.  I completely loosened the two captive screws on the shroud and released the lever on the bottom near the PCI slots.

It just seems like I am still missing something.  The part with the captive screw nearest the front seems to have come up a bit and is loose.  The rear though is digging it’s heels in.  It’s almost like there are tabs or pegs on the motherboard that I would need to move in a cardinal direction ?  There is nothing more in the service manual that I *haven’t* done.

Would love some clue - I’m trying really hard to not get frustrated and break something.

Thanks.
