If there was a demand they would find a way to make them fit. Even mini towers with a 5.25 support a front 240 mm rad. A single bay doesn't limit cooling, once you start sticking multiple ones in then yes
Everything depends on the price and how much you can get it for.
In my experience the i7 K CPUs are still expensive many years later, and it's not worth it.
A i3 10100 has similar performance to a i7 7700k. New mobo + 10100 might be cheaper. If you can spend a little more 10400 or 12100
I tried to perform AssRock to mouth resuscitation and flashed the bios chip. It looks like it wasn't the problem though. I used the green PCB flasher. It doesn't have the 5V flaw the black PCB version has.
Since the motherboard power cycles I suspect the power circuitry got damaged on the...
I find the mATX factor doesn't have a lot of new cases. All the new cases have glass.
Define mini C and Silencio S400 are the only ones I am aware of. There is the old Coolermaster n200, but it will only take a front rad.
The Silencio S400 has a horrible PSU filter design. You actually need...
I like new over used. I don't like cleaning someone's DNA out of the card, undoing mining BIOS modifications and trying to source non-counterfeit replacement fans.
If you're redoing the whole rig, buying a pre-built is a better deal right now.
They have been threatening Taiwan for decades. An invasion hasn't happened yet and won't happen because it would be too costly.
They will continue political and economic pressure to try to get a more pro-China government in Taiwan.
