Someone has figured out how to run
Coffee Lake chips in 100-series and 200-series chipset motherboards with just a BIOS flash. If you already have one, it can't get cheaper than that.
Considering many of those are overclocker-friendly motherboards designed for 91w TDP CPUs, the 95w TDP 6-core chips may not be much of a stretch for them.
Note that eventually Intel may release a microcode update to block this conversion (because they are losing sales of new chipsets from it), which would then limit you to older BIOSes released before that. This is similar to how everyone was overclocking locked non-K Skylake chips in 100-series chipset boards--if you want to do that now you'd have to use an
older BIOS, obviously one without the Meltdown and Spectre mitigations. While the current microcode has them, more severe ones (with greater performance impact) may turn out to be required later.
