Its funny how he asks that he wants a PREBUILT, alright he doesnt want to build it. Simple. Yet people still keep nagging him to build one like shut up let people who know bout prebuilt ones help him. But saying of which there are companies that do custom build so they give you options on the gear you out in, advice and options depends on what the computer is for and makes sure it all works. Saves you countless hours may cost more but hey people complain theres not enough jobs around might as well let someone keep there job.
