ATI Radeon HD 5770 1GB NOT for mac pro

I ordered a new video card for my 3,1 Mac Pro and accidentally ordered the ver that doesn't say 'For Mac Pro' not realizing that there was any difference. It seems that the video card should work, if I could get it in my tower! The difference between the two ver seems to be the length and shape of its support arm(can't figure out what to call this part), the FOR Mac Pro ver is an inch or so shorter than the other one.

I saw someone suggest cutting it off with a hacksaw, which I'd really rather not do. So I was wondering if anyone has tried removing the arm/case part? It seems like it might work, but I'm concerned about it exposing any important parts, it is covered with the important legal stickers.

Or does anyone have ideas short of the hacksaw plan to get this bad boy to fit in the darn machine?

Believe me…there was no accident about it! The Macintosh version of the Radeon 5770 costs at least twice as much (if not more) than the Windows version of the 5770. You DEFINITELY would have noticed this if you had ordered the Mac version.

I think that the Windows version of the 5770 came in different physical configurations. As an example of that…here's a Windows 5770 video card that does not have that "extra" part (the extra length):




With the Mac version of the 5770…that "extra" part is retractable:




If that "extra length" part is not removable (with screws) or isn't retractable on the 5770 you have…you're probably going to have to cut it off as you mentioned (or return it).
