My first computer repair, (epson 486) I left the drives and extra memory in when I sent in for repair. It must have had something really wrong as I got back a new machine without the hard drive and extra memory I had installed. It took a little bit to discover what was going on. Long hours on the phone trying to get those back (or something back.. that machine was maxed out at 16mb? of ram..)
