In order for a developer to get a 'certificate' for their app (that is, have it registered so that it doesn't trip the Mac OS's Gatekeeper app, blocking it from being installed), a developer has to follow a number of rules laid down by Apple. There is a lot more to it than just paying $99. Keep the screws with their relevant component by screwing them back in the holes either on the component or on the frame or by taping them to the correct location.I'm sure that the OpenOffice folks know all about it. Keep careful track of the screws, as well. You can take pictures before each removal or write it down. If you are rebuilding the computer, be sure to document what area you removed components from, the order you removed them, and what cables attach to each part. The metal inside the computer case can be sharp, so you might want gloves, as well. You will need a small Phillips-head screwdriver and depending on the manufacturer of your components, possibly a flathead screwdriver. If it’s not moving, check for more attachments that are holding the component in place.

In each case, no more than a small amount of force is needed to remove the part. Components can be attached to the case with special clips, screws, or by insertion into a holder.

Generally, the process is to unplug all the cords and cables connecting a component to other components, then remove the part from the case or frame. If you can’t access a particular component when it’s listed in the guide, skip to the instructions to remove the other parts until you can reach the original component. Our guide covers the most common ways computers are put together, but computers and manufacturers can vary.
