Ask if you can get something other than Dell.Get an HP or something.
though i could easily build one or find an amazing one on newegg or yes, even an HP. my dad doesn't trust that id make the right choice. So he chose his favorite DELL. But i can still customize every part of it besides the case.
tell your dad Dell isn't as good as HP or some others and show him online reviews or something
Please, please, please tell him not a Dell.He'd be making the biggest mistake. The quality of the parts is sub-par and they overcharge a bit.You can get an amazing computer from other companies, such as ibuypower, cyberpower, or even Acer and HP.
he would never let me buy from ibuypower or cyberpower, If anything his only other brand he knows exist is HP xD
