This is true.
We use ASRock Rack servers, mainly because the only option for our industry are OEMs like Supermicro and ASRock. Dell and HPE are non-starters, except for our "storage" offering.
Back in 2019, HPE was a good midrange option. Then came ASRock Rack who obliterated HPE with the X470D4U, relegating HPE to high-end enterprise servers. But also made Ryzen-based VPS hosts including yours truly, BuyVM, et al.
