Looking at it, it may be easier to do with a regular screwdriver if the
drive is opened at 45 degrees rather than 90.

Ratchet right-angle screwdrivers are also an option, as are ball-end
allen wrenches or offset-head screwdrivers.  None are particularly dear.

In any case, as I've said, I'm not about to hoist my 7970 into a rack.
I lost enough skin just getting it out of the truck into the shop.

I may, however, go prowling for a lowboy EIA rack...
