    The Hard Drive

    Laptop IDE Adaptor A laptop hard drive is one of the easiest parts to integrate into your new PC. The reason is that the laptop hard drives and their desktop counterparts share the same interface. So, If your hard drive is SATA based, all you have to do is directly connect it to the SATA data and power cables on your motherboard. If the hard drive is IDE based, you may need to purchase an adaptor like the one pictured on the right. It allows you to use an IDE laptop hard drive with a PC IDE cable.

    A hard drive larger than 60 GB in capacity should suffice for this task.

    The LCD

    Utilizing the laptop LCD on your desktop is a slightly trickier proposition. A laptop LCD communicates differently with the motherboard as opposed to a standard VGA connection on a PC. So you would need to first identify the model and manufacturer of your laptop LCD and purchase the required adaptor for it. The adaptor is not cheap any means, so make sure you really want to use it.

    Another issue withl aptop LCD screens is that they are not really suited for PC usage due to their limited viewing angles. Their low brightness is also another issue.

    You can purchase a VGA controller card for your laptop LCD from EarthLCD or Aurora IT Systems. Once you have connected the LCD to the adaptor, set up the LCD at a convenient angle.
