-Asking/convincing my parents to buy me a gaming pc

[Santtu]

Hi!

I'm 13 years and I would want to get a gaming pc, but I'm little afraid to ask them (That's not a huge problem). 

I'm not sure how to ask it the way that they'll let me have one or when is a good time to ask.

Btw my first plan was to build one, but the markest are quite shitty (thanks to miners) so i looked pre-built system and they were cheaper then my build plans. So I'm planning to get a pre-built, where one reason "You would learn to build them" goes away.

Tell me should I build now, build later when the prices sometime come down or buy pre-built now.

Also, I cant get a summer job anymore the time went long ago.

Other points are that I get good grades, I do always the stuff that my parents ask, I don't argue with them, on and on.

Please give me advice if you can, I have been pushing this for a while.
