Back in the days when I was a engineer in a computer shop, three little times allways pop to mind. A customer when insisted on buying a pack of blank cd's just to see what would hapen, even know we insisted they would not work when he did not poses a CD-RW. Another customer who came in and wanted to buy an ATX case, on hearing that the cheapest we had was 20 pounds, he seemed shocked, saying he wanted more then one, he infact was interested in the 2000 we had. Puzzeled I asked why, it seems on the recormendation of his IT Support officer, he needed lots of ATX cases to "build a firewall". and lastly A young man of 15/16 yrs came in and bough a CD-RW drive, confident he could take the nice new drive home and fit it him self. near the end of the an older gent (namly the boys dad) came in carring a PC with the sheepish lad behind him. On hearing that the PC 'blew up" with an array of sparks and smoke after the fitting of this drive, In pure curiosity I removed the side panel to find that insted of connecting the 2 required cables (the power and data cable) the young promosing engineer had indeed pluged them in, and also striped a live lead inside, soldered speaker wire to it and then soldered the other end of the speaker wire from the live lead to the pins for selecting slave or master. The result was the frying of the CD-RW, and the speaker wire melting and catching fire. When asked why on earth he would do this the answer was simply, I though it was what I had to do.
