Hmm...ok. I want to see if this is possible to explain without sketches, so let's see how clear i can make this.
1) You have a hinge with a strong spring that lifts the lid under it's own force. Therefore, without adding anything else in, you now have it open. Now to close it.
2) You hook up a latch that will release while the computer is powered up. So from closed, power up. Latch opens, spring pushes up your lid.
So far, this is the easy part. Now you need to find a way to get the lid to close again after power off. There's a few ways of doing this.
3.1) You hook up a motor to some sort of pulling device (robe, bar, gearbox, whatever-it's the moot point) which pulls your lid closed after power off. Without main power, your latch is closed. Now, you can power a motor with the various points in the computer that provide power while the whole thing is turned off-there's 2 5 volt lines in the motherboard connector that can do this. Dissadvantages of this method are that there might not be enough power in these lines, and trying to draw extra can blow the internal fuses in the PSU or in the wall socket.
3.2) You get some capacitors to power the motor. As long as the power is on, the capacitors will charge. When the power is off, it flags a relay which allows power to the motor. This then closes the lid onto the latch.
4) When the lid is closed, it hits a switch, which stops power to the motor. In this state, the latch is closed as there is no power, the lid is closed, and the motor is off. Viola.
This isn't perfect, and could use some work. One person who's pretty damn good at this is CrazyBillyBob from these forums. He's always had helpful suggestions for me in the past when I worked on these systems.
Hope that helps!

Thanks alot dave very helpfull!
I will probably use the spring and hinge thing lol. I will proberly wire the motors for manual use though as I am not that good with circuits (but I am good at soldering!) so unless someone would be as kind to tell me what I need and how to wire it I think I will use the motors manually!
Thanks alot
Unfortunately, that's the problem with my method-it relies on the circuits. If you want a manual circuit, where you press a button...that's going to be a little different. The spring will not belp much...first, you need a way to control the latch. Or, alternatively, you can devise a system of up/down motors...hmm.
What have you got at hand? This might help with the eventual decision making. You'll need some kind of gearbox and motor, with some luck, 2 of the same to help with the weight of the piece.
Also, if you can post the dimentions of the door, the estimated weight of the door in Kilos, and what angle and direction you want the door to open till, I can probably talk you through some ideas.

Right lol-
I have two identical motors and pretty much anything to hand a may need!
As for the door I will let you know very soon!
Cheers
Sorry I have not spoke in a while but I have quite badley broken my toes so the project is on hold for a while :-(
Sorry guys!
sorry to hear that
but how did you do it
smashed my little toe into a door frame lol
-gaz
Ouch!.
Hope you get better soon and can get back to your mod.
me to!!! I really wanna start painting!
Thanks
