Can I change Laptop's Full Body?

Yes you can, best thing to do is get as much information about the model of your laptop and search on ebay, you may need to keep checking. People are regularly selling spare parts and the part you need is known as the bare bone i.e the outer casing or the shell. Though people tend to advertise the laptop by it's model number. Expect to pay between £40-£65 depending on whats wrong with it, make sure you ask what condition the barebone is as the last thing you want is another scruffy barebone.

I'd also contact Acer and see if you can get the part number and whilst your talking to them ask if you can buy it from them, else google the part number and you may find a third party company selling it.

Taking apart a laptop is a jigsaw though, ensure you take out the battery first and as you take each part out, lay them in a line and maybe draw a diagram of the laptop where you take the screws out from because it is very easy to forget where they all go when you put it back together again.
