Yeah, I'm ever-scouring the interwebs for cheap mobo "opportunities" (for a build). Hard to find really good deals.
Last good mobo deal was a bunch of supposedly-new A55M ECS FM1 (yeah, FM1, LOL) micro-ATX boards, that waltchan clued me in on. Along with some new (minus heatsink) FM1 dual-core CPUs for between $8 and $15 USD. Bought like ten sets of them, sheer overkill, LOL. Still stuck with a bunch of them, thinking of donating the parts to a local HS tech program to mess around with or something.
Or maybe I'll get around to building them, and donating the PCs. Did that with a couple of them already. They really don't make half-bad browsing machines, either with Linux Mint, or Windows 10. (Windows 10 install finds all drivers automagically; mobo is "certified" for Win8/8.1.) Not
quite as speedy in the CPU dept. as a Haswell G1820 Celeron, but still decent, especially if you overclock them 5-10%. Thing is, those K10.5 cores, were actually not half bad, and they have higher IPC than Bulldozer / Piledriver APUs, and higher clocks than AM1 APUs. So, they're kind of in the middle, performance-wise, and unfortunately, their iGPU is VLIW4, so no longer supported by current drivers, but Win10 automagically finds working ones.
I could sink to scrounging at a local Microcenter, they always have a stack of returned "open box" mobos sitting around, but ... who really wants to take a chance on those? Probably some bargains to be had, if you are adventurous , but I try to stick to "new" boards, or at the worst, "mfg refurbished", for customer builds, even for "donation builds".
There is this deal, an Asus H110-chipset micro-ATX board, with an M.2 socket, for $44.99 + $1.99 ship:

Seems like the best deal on a "new" 1151 board at the moment.
