So, yeah... I was lazy.... 
... But I kind of knew the "answer" to my (rhetorical) question -- Will (the PTR-N881) fit? -- before I started "testing" things out.
For starters, here's the test bed:
The closeup shot of the PCI slots is to answer a question that was posted in the SFF forum thread for this board. The PCB is brown -- and yes, it's a Revision 1.1 board.
And here's the N881 with the 80x25mm fan attached:
As you can see, the heatsink is offset just enough to accommodate the fan. Space, however, is still an issue....
The long story short is that the size of both heatsinks (the HDT-SD964 and the PTR-N881) plus the lack of available space on the X58M makes for a generally bad fit. Regardless of how I position the heatsink portion of the N881, it ends up rubbing against something. Though I was eventually able to make things "fit" by positioning both heatsinks with the fans pointing upwards, it would be impossible to replicate inside the case with the PSU in place.
And to further emphasize the lack of overall space on the board:
... The heatsink portion of the N881 runs up against the retention bracket on the back of the GPU. Granted, I could remove the fan and just "flip" the heatsink, but the N881 would end up brushing against the SD964 in some way, shape, or form.
For comparison's sake, here's the HR-05 along with the video card and SD964:
I'll stick with the HDT-SD964 for now... but I may consider getting the Noctua NH-U9B later.
(Or, just to match, the Thermalright Ultima 90... if only enginurd could "find out" whether or not it's decent.... )
