650$ gaming build (need advice)

[New at this hobby]

I want to build a PC because of the opinions on building pcs online versus prebuilt computers, because you can save money and enjoy building you own computer. Please give opinions and suggestions

looks like a decent build for the price, I might consider an SSD though.
