For those who have an older generation Mac or an old laptop and would like to utilize it in other ways? You could try converting it into a Wallmac.A Wallmac is basically a fully-functional, wall-mounted Apple Mac/PowerBook.
Great tutorial over at Wallmac.blogspot.com which includes pictures on converting your Macbook into a Wallmac. Similarly, you can also check out KitcheNet, a project which aims to provide an easy method to reuse obsolete laptops and desktops in a kitchen. There is also Wall-PC.
I would love to try out the Wallmac tutorial with my old Acer laptop, sure makes a nice addition to the room ^^;
