I'm thinking of buying the different parts, and building myself a computer instead of buying one.
A lot of people say that the big advantages of this is that you pick out what parts you want to put in and the whole thing costs much less $$$ than if you want to buy it from the store.
I haven't started on the "buying parts" part, but I have done some research on different sites on how do assemble the parts and so on... I guess for now the only scary part for me is how to set up the OS, because each site tells me differently how to set it up.

Can anyone give me some tips about this?
If you have done it, can you tell me some do's and don't?

P.S. Also where is a good place to buy the parts? Online, or the store?

Thanks a lot!
