Revisiting this thread in a few months when lower-cost 300-series Intel chipset mobos should prove elucidating.
I look forward to building more entry-level i3-8100 rigs for people, with B360 boards and cheaper DDR4-2400 RAM (the fastest that the combination of i3-8100 (2400) and B360 chipset (no DRAM OCing) support.
Assuming that slower DDR4 might drop in price slightly, these components could replace the G4560 in ultra-budget builds. Certainly enough for the non-gaming crowd. Maybe investigate Intel SRT / Optane caching (which, being an i3 rather than Pentium, should support).
Here's a build at Newegg. I chose a 512GB Adata M.2 PCI-E NVMe SSD, over the Optane route, after reading the reviews on Optane. I also chose a 550 Seasonic Focus+ Platinum PSU for $100, because modular and 10-year warranty, as well as a current $20 rebate making it $80.

I think that this is a really kick-butt rig for ~$650 AR, although it does not have a dGPU. Add a GTX1070 ITX "shorty" card, for $380-400, and you'll be rocking for gaming too.
Case was just a cheap, but windowed and 2x USB3.0 / 2x USB2.0 front-panel ports.
