OK if none of those last options worked for you its now time to crack it open. So lets start with the simple components and work our way up. So the 1st component is the cd drive.
1.Make it into CD player.
Yes, this one is very simple. All you have to do is take the CD drive and the power supply out and connect them together like they were in the computer. If your PSU is the ATX standard to make the power supply work without the computer short one of the black wires and then green wire in the big motherboard connector. You can use a piece of wire or a paper clip or just chop them off and then join them. Now all you have to do is hook speakers or your hifi into the headphone socket on the front of the drive. Then press the play/fast forward on the front of it.
2.Make it into a laser pointer
If you have a DVD-RW and are not planning to use it in another computer you could turn it into a laser pointer. USE with caution
3.Make it into a safe
This makes a great hiding place. What you do is you hollow out the drive and you can use it as a great hiding place! If you are going to attempt this and are smart enough and can keep the motor mechanism (ie open and close with the open/close switch) I would suggest cutting the two black ground wires off the power connector and putting them through a basic on/off keyswitch. Therefore if you do let slip about it they wont be able to open it with out the key.
4.Make a Roulette Wheel
This is a brilliant idea. If you can never decided who is going to get the coffee or are just indecisive this is the gadget for you!
