Best budget gaming PC builds?

Hey guys... can someone help me put together the cheapest possible gaming rig? I'm looking to hit around 120fps in Fortnite, plus LoL and CS... just the tower, no monitor or peripherals needed. Budget is up to $4,000—but honestly, if we can pull it off cheaper, even better. I'm looking to buy around Indianapolis or just order online if they offer assembly services.

The power supply is an EVGA 500 W Bronze.
The Kingston 480GB A400 SATA3 2.5" SSD (7mm).
The SilentiumPC Signum SG1 Pure Black case, just the chassis itself without the power supply.

I guess I should probably mention that I’m looking at two of them. Maybe just thinking out loud. Corsair 8GB DDR4 2400 Value, COR-CMV8GX4M1A240C16
The VGA XFX Radeon RX 570 RS 8GB features 3x DisplayPort, 1x HDMI, and 1x DVI-D outputs. P/N: RX-570P8DFD6.

All things considered: $1332 Center

Is Crucial an SSD worth picking over Kingston, especially if it comes with a 5-year warranty? Also, I'm looking at an ASRock motherboard with four RAM slots.$50
