And by possible contrast, what does you company actually use?

Prefer Dell EMC but we're a HPE shop.

My second choice is IBM.

Fujitsu Primergy

Also the Fujitsu Primergy.

We bought a Dell Server with Windows Server 2012 Essentials and it's still working.

I've haven't been anywhere that's used those. Cool. Been pretty stable for you?

That reminds me, we have a couple 2012's we'll be upgrading soon. Fun, fun

I'm retired now, but numerous clients used them for the past 16 or 17 years before I retired. They're fast, fairly quite, and very stable. Even the disks last quite long too. They manufacturer their own chipsets. 

They're mainly sold in Japan, but I've heard of them being shipped to some European countries too. Very popular in the banking and government world. They're a little pricy, but they're good. This is the only thing I could find on them in English.

From the little I've found on them, it seems that the larger the order the more willing they are to work with you on price. Based on user experiences I've looked up anyway. That's how HPE is too.
