I'd look at some shops that sell optimized systems for recording. Some (few) also list the built-in HW components.
I would orient myself on that in terms of mainboard, CPU, CPU cooler, memory, SSD. Maybe even a dedicated GPU.
Intel still seems to have the nose ahead when it comes to DPC latencies. At least with the Threadripper platform but maybe also on the mainstream platforms. Better inform yourself on that topic.
This is important for an agile system so that the probability of audio drops is as low as possible even with smaller ASIO buffer sizes. This is especially important if you're recording with VSTi's and need to record with low RTL under 10ms (ASIO buffer sizes between 64 and 128 samples) while the backing track is eventually also still using VSTi's and is not yet rendered to a wave file.
For consumer stuff I personally would prefer ASUS over Gigabyte, MSI and ASRock.
I think Asus still has better support and eventually also technology/design.
When people needed CPU microupgrades via BIOS against Spectre and Meltdown I read that ASUS reacted fastest and for a broader range of mainboards compared to the other competitors.
I got an extremely nice Xeon based server board from Supermicro, but I am not sure how good they perform in the mainboard market for plain desktop systems.
1-2 years ago I heard a real tragic report from a recording user who bought a Gigabyte board. It sounded like an Odysse for him and the simplest things like boot order and stuff like that was not running on this mainboard. So to say the simplest things where you wouldn't expect any problems. And also in other context I have Gigabyte boards not in good memory.
But I also know that vendors can also have bad luck with a certain board and the next follow-up model works better, I had that with MSI, but at the end still was not really happy to get a stable Firewire based platform.
At the end I would nowadays either follow the approach to look what other companies use to build an audio PC (all execpt AMD based) or I would concentrate on a Xeon Build with Supermicro or take an ASUS based system.
But like always .. no guarantees .. every system is a bit different.
If you want to be on the safe side then get a turnkey system for audio, this can safe you time and frustration.
My preference would be at the moment: Xeon based, server or workstation board with a simple BIOS that is not grafically bloated. No overclocking (-> stability + less wear) where you easily can use legacy-boot and turn off all the stuff like "secure boot" etc, which only makes administration harder or things like dual boot or deployment of other operating systems.
The downside is, then you still get no good board with Thunderbolt support if you would like to have it as an option.
Like always, its not so easy to get all wishes and requirements under one hat ;-)
