Saw this from Umart email, seems a good deal considering NUC7CJYH is around $200 which CPU is J4005, this one has a better CPU.

Well, that i5 probably doesn't support 2K res display properly, let alone 4K. Video decoding, the old 2nd gen core i5 is lackluster. Also, the power draw is different. Storage, it's likely limited to SATA3. Sure, the m.2/NVMe on this is only x2, but still better than SATA3.
I have an old small form factor pc that I really want to retire it. It's a second gen core i5 too. Yes, still beats low end NUC like devices, but still draws too much power. I get the appeal of using it as a router, but people doing that are tech savvy enough to know what they want.
