My initial query was the following:

I got 3 different answers. Two of them said it shouldn't be done, while
the third one said there were no problems to it. Here are their replies:

All of the vars that i have talked to in my area (Colorado) tell me i can add
the 424 drive, if i can find space to put an extra fan.

Henry Bryant - FSE (hbryant@braves.East.Sun.COM) said:
It should work fine with no problems; make sure you have the target(address)
set correctly; the 424mb drive will be standard in the future desktops systems

I so happen to have an answer from my Sun rep on this:

Thanks to all!
