There's not much reason to put it in a gaming machine. It's pure compute performance, used by researchers and other applications where CPU processing power is needed. You can't use it the same way you'd use a traditional CPU unfortunately.

Interesting idea, I wonder how bootloaders etc. will work on something like this though.

My only guess is maybe the audio chip isn't well grounded/isolated from the rest of the components. Maybe try this with the motherboard out of the case?

Both are reputable, the latter of which donates a portion of your purchase to charity.

Green Man Gaming and Humblebundle come to mind.

I hate to be the 'Why not Ryzen?' guy but honestly it makes no sense to choose Intel when you're going to perform multithreaded workloads and run virtual machines (which you need as many physical cores as you can get for). At the price of the 8700k, it's honestly much more worth your time to go with a top tier Ryzen product. The Hyper 212 wouldn't be adequate for either, especially in a rackmounted case with restricted airflow. Look into a higher tier air cooler such as the Dark Rock 4. You don't want to end up thermal throttling those hot Intel chips. And if you do still stick with the 8700k, I'd ask why are you using it on a motherboard with no overclocking support. 300W is not much more than you'll honestly end up using but the reliability of the power supply is questionable.

The contacts might be shorted out. Lay it out flat and try it again.

Can you show us a picture of what you did? Usually these membrane keyboards have a thin plastic PCB that links up with their mainboard. I'd probably just fold it over so as not to cut them off, but even then it's a bit too much effort to just have a TKL keyboard when a new one isn't that much.

Most modern board have protection in place of this. Don't panic man, I once shorted the VRMs on an old AMD FX board, a day later it worked fine. There's only one way to find out though, go ahead and double check everything, take out your GPU and leave only one stick of RAM, then turn it on.

Make sure you have the latest BIOS update for your board, Ryzen can be a bit finicky when it comes to RAM.

This is a known Ryzen issue, undervolting is kind of weird on the platform. Even when it does work, you get worse performance at the same frequency than what you used to. It seems to be mostly a software reporting problem. https://www.gamersnexus.net/guides/3494-amd-ryzen-3000-undervolting-offset-override

EK fans are a good bet, they have great static pressure and are quiet enough for most use cases. Noctua NF P12s are a great alternative if you want quieter fans, but bear in mind they are more expensive.

More than likely it just hasn't been updated on the motherboard manufacture's website, it's a 99% shot that it will work fine.

Maybe your motherboard/chipset? If you swapped in a new GPU that could be the only thing asides from the display cable being grounded to case in a strange way that could do that.

If these are your options then I'd go with the beQuiet, definitely the most reputable of the bunch. Otherwise, consult this list:
