Budget is about $1500 +/- $200
This will be over your budget. But it is probably where I would start with a Coffee Lake build. If I could not afford this, then I would not look at Coffee Lake until the pricing comes down some.
You really want to get a decent motherboard for Coffee Lake, which will cost you more. You can get by with a cheap motherboard with the Ryzen CPUs because the AMD CPUs hit a hard wall at 4.1ghz. That is not the case with Intel. You will need a decent motherboard to get high and stable overclocks.
But I will say this, this system would be a beast. lol
