Assembling a PC is pretty basic usually. Most parts just attach to a slot on the motherboard. There are several decent guides on the internet which walk you through the process step-by-step in detail. And if you still weren't certain about something feel free to shoot me a PM and I'll answer any questions you might have. I've been putting PCs together for the past 13 years or soYeah, I heard the same about Alienware. I've only ever used Dell and Intel, but I don't know how much more expensive their already built systems are compared to building one yourself, with the same components. Personally I think if I get the components on my own I'll make a dumb mistake that's common sense to people who know this stuff.
