PC or a mac

Hello everybody this is 2cool4games, I am just wandering should I get a PC or a Mac for my next computer. I know mac doesn't crash as much as PC but I think I should learn how to build my own Custom Pro PC. It cost a lot cheaper then a mac and plus you can learn how to upgrade your computer if it need's more memory and stuff like that. Even my big sister know how to replace a mother board/ Why can't I? My mom says that I should wait until I am older to build my own computer/ I want to build a computer whenever when I have a chance. It's going to be a gaming desktop that use's three monitor's and the latest processor. Do you know what I think about mac's / I know they don't have a lot of problems until it gets old. When it's old my dad's computer at the office it can't use the internet right and stuff like that. But with custom Pc's you can upgrade you Custom PC whenever you want to. Thank you for reading my blog/ And also I am trying to save up for a gaming keyboard for my gaming. Do you know why/ Because it has macro keys/ Thank you for reading my blog again.
