Here's my 8yr old daughters build.

back story:

i built my setup maybe 3 or 4yrs ago. she always play minecraft on the tab. she tried it on my PC and she fell inlove. WASD keys was hard in the beginning, but with in a week she got the hang of it (such agility on them fingers now tho, geezus when we play, her fingers just taps taps taps taps.) shes been wanting her own for a while, so last year i decided that this would be a great christmas present.
i asked her if she wanted a Switch or a PS4 instead, and demanded that she wants PC. she even game me all her savings in her piggy bank. I have been wanting to upgrade my 1080sc anyways to an RTX 2080ti. unfortunately, or luckily that the RTX is always out of stock. so i decided to just use the money for a 1080ftw3 for my pc and just hand her the 1080sc. it worked wonders. before you think that im rich, the answer is no. im just a humble cook that works 14hr days 6days a week. i put money aside for my pc spending.

she actually built it (im just supervising and telling her what part goes to where, and also explaining her what each parts do, and also tidying it up.).
