Prebuilts will fleece you like there's no tomorrow. Not only are they considerably more expensive (I've seen +50-75% on price before) but they also often "smuggle in" second-rate components that aren't otherwise selling, simply by not giving people a choice or not telling them specifics. Who manufactured your GPU for example can be a pretty significant difference.
If you're spending that much money I'd strongly consider buying components separately and assembling them. If you don't feel confident assembling them yourself, look around your local area - very often there will be shops or freelance techs who will offer assembly services. You can pay them 50 quid or whatever and they'll put your components together for you in the proper way. That'll still save you massive amounts of money over some prebuild company, and will usually leave you with better-quality components, too.
