It shouldn't be too hard, because most pieces of the computer come with a guide how to install it, and just follow the instructions closely and you'll be fine. Use the internet to look up terms, or there may be a term guide in the guide. Also, if you have any friends that are good at computer hardware, ask them to come over to help you, it shouldn't take more then 1-2 hours. It's actually pretty fun to build a computer, like waffle said it's like lego's.
