I've never built a PC in my life. But so far, what I want built is based on this:
More than likely it would be cheaper building a PC from the ground up based on similar specs in the link. But I do want to make sure I pick quality components. It's a work in progress mainly based on price. I'm hoping to spend no more than $800 including a monitor.
From those premades at Newegg, I suggest this one if you want to stay below 800$ including the monitor: https://www.newegg.com/Product/Product.aspx?Item=N82E16883102537
At 630$, it would leave you 170$ for a new monitor. The 1050 ain't too powerful at gaming, but considering high-end gaming doesn't seem to be the priority right now it should do fine for now and could easily be upgraded later on.
