Do you like just buying computers are buying the parts assembling them ?
I personally hate made computers i mean assembled, i like buying the parts i like and assemble them by my own. Even though people say that the others work faster and better cause they are assembled in " harmony" with each other (the parts). i still don't think someone could make the computers better than i do
there aren't really any variables or possible mistakes so , why not do it on your own?
