I would like to build a Ryzen desktop. Can anyone recommend a good

I'm planning on a first-gen, because the second-gen has similar
stability problems as the first-gen had, and AMD hasn't released
errata for the second-gen yet (as far as I know...I would love to be
wrong).
IIRC the weird freeze/segfault bugs were only in the early batches of
1st gen. If you get 2nd gen, you're *definitely* getting a stable chip.
My R7 1700 is from Aug 2017, never had any issues. So a 1st gen bought
today should be fine too of course, unless *somehow* you get very very
very old stock.
I would like to be a cool kid with a Threadripper, but I can't
justify the cost, so I'm thinking maybe a Ryzen 7 with /only/ 8
cores. :)
Yeah, yeah. Good discounts on 1st gen Threadripper can be found these
days though… but still there's board cost + RAM cost (you have to
fill up 4 memory channels on TR if you want performance to not suck).
Ideally, I want an Intel NIC, ECC memory support, and a 3-year
warranty.
For ECC, you can google board name + ecc ram. You can often find
reports on forums/subreddits/whatever.
Since you care about warranty, you probably don't care about
overclocking, so do not watch the following videos: B450 boards —

But still, good power delivery is important for an 8-core even at stock
settings, so avoid the latest ASUS TUF board, and super cheap boards in
general.
I have an MSI X370 SLI PLUS. The firmware is good, RGB lighting support
is good (most important thing! lol. controllable under FreeBSD with
https://github.com/nagisa/msi-rgb), the VRM is okay but not super great
(8-core @ 1.39V 3.95GHz → ~100 ℃ without any direct airflow over
the VRM heatsink). NIC is Realtek, recognized by re(4), I never tried
it (I use a Mellanox card). Audio is Realtek, works fine 99% of the
time (very occasionally sound stops working, sysctl
dev.hdac.0.polling=1 brings it back). There is a pin header for the SPI
flash chip to recover a failed firmware update (I actually did this
once :D), but the pins are tiny (2mm instead of the usual 2.54).
