Gaming PC build under $400?

Hey everyone.

So, I'm looking to put together a decent gaming PC that won't break the bank. My budget is roughly $900, so if you have any suggestions on what offers the best bang for my buck at that price point, I'd appreciate it.

I was eyeing this bundle, though I'm not entirely sure if it's actually worth it. I was originally aiming for a Ryzen 5 2600, and I think I saw some listed on eBay for about $233. Just to clarify, I don't need to include an HDD or an SSD in this budget.

As for the graphics card, I'll probably just pick up a used one that hasn't seen too much heavy use.

The r5 1600 AF is basically identical to the 2600 $300
Asrock A320M-HDV R3.0/R4.0, AM4 $125
DDR4 8GB (1x8) Corsair 3000 MHz
Dominator Black CL15, HX430C15FB3/8 $107
All of that comes out to about $230
That bundle at Micro Center includes $550 the older first-gen Ryzen r5 1600

Anyone else weighing in? I suppose this Ryzen seems like a decent enough choice.

DDR4 8GB (1x8) G.Skill 3000MHz AEGIS, F4-3000C16S-8GISB
MS midi tower Hunter

Total: $682 Newegg r5 1600 AF

You’ve got about ~$233 left over for a GPU; I'd suggest picking up something used. Look for an RX580—maybe the 8GB version or the 4GB one.
