But I don't know how to build it...

In most computer shops for like $30 they will build it for you.
Last time I built up my computer I nuked my motherboard. Would have been cheaper to have it built :sad:

Do you know the name of the computer shops that can build for you?

just loook around localy and phone in to the shops and ask and they should be able to tell you
