Hi, Sorry first for the misplaced posting but it seems that its the only solution. I have mailed to all HP representatives around the globe but still my problem is not solved. In fact, i need 4 pieces of that little plastic rails, they are used to mount CD-ROM or a Floppy drive, in a C240 drive enclosure. If anybody have some left please mail me faster the better, because my box neither has a cd nor a floppy. regards chris
