You're telling someone who just gave 3 wholesale laptops as options to just jump right into building their own? There are stepping stones needed to reach that stage. First, just anything you see in Walmart, Costco, etc., will do. When the user gets tired of that, then it's on to Cyberpower, IBuypower, OriginPC and Digital Storm. This is so they can see first hand the parts going into their pc while navigating through the configurators. After they've experienced the terrible customer support of prebuilt gaming pc companies, and only then, will they have the motivation and drive to dedicate some hours into researching how to build one themselves.
I'm currently on the 2nd stage as my Cyberpower PC has been going strong for 2 and a half years now with no kinks whatsoever. Therefore, personally, I'll never build one myself. Don't fix what ain't broke.
