Prebuilt computers are always more expensive and there is a great risk of damage during transportation. It is better to secure PC parts individually and build them yourself. (Really not hard to do. It is mostly Just plugging parts into the ports that look like they match and putting some screws in.) If you are insistent on buying a pre-built then make sure to buy from a company that focuses specifically on selling pre-built computers. Do some research to find out how they package their products during shipping. Also, make sure you understand what parts are actually good by checking their specs and what each one mean.
