faster int. hd question

[Malcolm Hamilton]

Thank you to all who've weighed in on the faster internal hd 
question.  It seems that some of you think the 7200RPM drive does 
indeed make a discernible speed difference; others aren't so sure the 
difference is enough to justify the extra expense.
I might have gone for it nonetheless, but Robin's warning, about the 
extra speed causing the drive mountings to loosen, has scared me.
Robin - is this the kind of thing you can fix yourself, by opening up 
the back and tightening the mountings?
Thanks everyone,
Malcolm
