I'm guessing you've already got a monitor?
This is what I'd suggest: https://classic.pric...st.php?l=290609 Comes out to ~$1370 buying from PC Force and Ascent. The extra ~$30 could probably replace the CPU heatsink with something quieter.
The case, RAM, GPU and mobo all have RGB lighting, and mostly that hasn't done much (if anything) to the price.
The real problem is, to get a decent GPU in to $1400 requires a cheap CPU. Fortunately though cheap CPUs are nowadays quad core, which are adequate.
You could save about $50 on a SATA SSD instead of PCIe. If you got a smaller one you'd probably need to add an HDD, which probably wouldn't reduce the price overall, but would give more total storage.
