Computers from time to time need to be upgraded, completely rebuilt or just disassembled to salvage for parts. One type of computer that is good to salvage for parts or to upgrade is an Acer Aspire for the desktop. This particular desktop computer has many models with slightly different case designs with parts that may not work together.
Unscrew the fasteners from the back side of the case to remove the side panel. The side panel needs to be removed in order to access the internal components of the machine. Slide the panel back, and it should come right off.
Remove the screws that attach each PCI or AGP card to the case. Gently pull out the PC or AGP card from the motherboard and set them aside. Depending on the type of PCI or AGP cards in the system, they could be reused.
Remove the screws that are used to attach the CD-ROM or DVD drive. There should be two screws on each side of the drive. Make sure the power and data cable has been unplugged from the back of the drive and slide it out the front of the case.
Unscrew the bracket or remove the screws that support the hard disk drive. The hard disk drive on an Acer Aspire is normally mounted on the front part of the case directly under the CD-ROM or DVD drive. Unplug the power and data cable before removing the drive.
Remove the motherboard if the computer case is not going to be reused. If the computer is being rebuilt with new components, nothing else needs to be removed. The motherboard is going to use a combination of metal screws and plastic connectors.
Gently remove the plastic connectors and unscrew the metal screws. Lay the case on the floor so that the case is flat when removing the motherboard. Lift the motherboard out of the case gently, so that nothing gets broken.
Decide what to do with the empty case. Set it aside if it it is going to be reused. The power supply does not need to be removed unless it is not working.
Unscrew the screws on the back side of the case where the exhaust fan is for the power supply. Pull the power supply out of the case. The Acer Aspire has now been completely disassembled.
Save any working parts and components during disassembly that can be reused in another machine.
Never open the case to a computer without first unplugging the power cord.
