I've been a Thecus.com NAS consumer for well over a decade. I personally own two now.
I bought the N7700SAS, in 2009 when it would support a max of seven 2TB drives, with about 10.5 GB RAID5 storage.
In all this time, it's got about 98% uptime and I've only had to ever replace 1 drive. Hot-swapped it, took a day'ish to rebuild the array and been ROCK-solid ever since. Yes it is still up and running.
When that space wasn't enough, I bought the N5550 and initially put five 4TB drives in it, RAID5. Been ROCK solid for 4+ years with zero drive failures. Just a year ago, I swapped out the 4TB drives for 15TB drives, rebuilt the array and its had 99.99%+ uptime on an APC UPS. So, even with house power-outages due to storms, its remained fully up. Firmware upgrades have been painless and they just work. XFS has been natively available for a decade+.
Highly recommended and have NEVER been disappointed with Thecus. I've made suggestions to colleagues about them, and at least 5 that I know of have invested in Thecus. I've made suggestions to several business looking for a quality SOHO NAS over the years and they've all been happy with what they've purchased from Thecus.
Disclaimer: I'm only a consumer, no affiliation (and no commissions, damn it).
Today, the N5810 could be a worthwhile investment. The PRO version is on their homepage demonstrated. Their site has good pictures of all their equipment. Their SPEC lists are impressive.
The company is out of Taiwan, and their documentation reflects it (i.e. some poorly translated english), but most of it is well-put together. The PRO version comes with a mini-ups... your choice on the value/need of it.
After reviewing your requirements; the 5810 tower will meet most of your needs, but:
- It only comes in a 5BAY model. Still, you can easily put five 16TB drives in it... so capacity shouldn't be an issue.
- Almost all your other requirements are easily met by their standard functionality; check out their SPECs
- The only thing I believe it would be lacking is the 10G network(s); it does have dual NICs and can do bonding to accelerate throughput, but it will only be two 1G LAN ports.
Having said all that, their next model up which might satisfy you, is a rack-mount, the N8910, which will then meet the 10G dual NICs (review their compatibility list); again it is RackMount. It does have a front-facing small LCD indicator screen. It does support 8 internal drives, and capacity of up to 18TB drives spinning disk (WD Gold Series). Various SSD drives are also supported. A simple search found a price of $1799.99USD for the case itself.
As far as system RAM in any of these, what they provide IS adequate. On my N7700SAS it came with 2GB and hasn't been a problem with TONS of reading/writing; like I said, I'm still using it today. Had iSCSI partitions on it for a while when I was playing in that arena and testing at home. Worked just great.
My n5550 came with 4GB and I upgraded it to 8GB. Didn't NEED to, didn't have a problem, but wanted to. It was an effortless upgrade and been rock-solid ever since; just wanted to see if it could be done and what the issues might be (none!). YMMV Thecus does tell you what the MAX RAM upgrade capability is in their SPECs, so that is helpful info to know right up front.
The underlying OS is a busybox-based linux (which may, or maynot be true for the N8910). It works, is minimal and I've had no issues with it. Gaining SSH access was initially a bit of a trick, but do'able after a few internet searches. Their systems usually have an HDMI port and USB ports, so a monitor/keyboard are able to be added and used that way. In both of my systems, simply having SSH access has been more than sufficient; never have needed to attempt connecting a monitor/keyboard. But I've not had crashes like you've described, either.
Hope that helps.

BTW, did I say "LED strip". I meant LCD text display - when happy it
showed the IP address and a little status, when unhappy an error
