Needing Advice on buying Gaming PC

[leon343]

I have a friend whose nephew (7 yrs old) wants a gaming PC for christmas. I was going to offer building a PC but she is scared of the big price tags, I think 400$ would be her maximum budget but she would rather it be less than that. I believe the nephew just wants a flashy gaming PC, I'm certain he would not notice performance or anything like that. I would imagine he plays games like Minecraft, Roblox, she mentioned a game named Pods? so the PC doesn't need a GTI 1080.

Would this be a good PC?

CPU: Fx -8320 black edition
GPU: Radeon R7 260x
8 GB of ddr3 ram
1TB WD blue drive 7200rpm
Motherboard: MSI 970A-G43.

If y'all have any links to a computer with a reasonable price, feel free to let me know. Thanks in advance!

*Update* She has agreed to build a PC if it means a better price. Feel welcome to leave your budget builds in the answers and if you can, how good the performance is on your machine.
