If you are getting an Alienware for PC gaming...You're doing it wrong.
If you're getting an Alienware, you're doing it wrong.
I have major trust issues when it comes to handing my money over to people (especially when it's in the range of thousands). I have seen people with custom PC's breakdown too many times resulting in them having to money on parts too many times (me being one of them.). If I can find someone with more than adequate skills I'll be more than happy to have them build a PC for me; until then I'll stick to Alienware.
If you're interested, I can help you with building a computer.
I wouldn't pick the various parts for you, instead I would give advice, and explain my reasoning for advising you on specific parts. I've done that for friends in the past.
I've had a few friends ask me to build a computer for them, but I'm not comfortable with using other people's money(unless they're actually giving me those money), but I'm more than happy to give advice and suggestions.
