with GNU sed version 4.1.5, I found "i" or "I" working for "case insensitive" replacement.

Code:
$ echo "UnIx" | sed 's/unix/BEST/'
UnIx

$ echo "UnIx" | sed 's/unix/BEST/i'
BEST

$ echo "UnIx" | sed 's/unix/BEST/I'
BEST

And if you are using awk

Code:
$ echo "UnIx" | awk 'BEGIN{IGNORECASE=1} {sub(/unix/,"BEST");print}'
BEST

//Jadu
