Maybe call them server units?

We are going to have a Dell PowerEdge review tomorrow. We call that a server or more than one servers not server units so that would feel strange to me.

I see, it's not easy to just call them "server units." Good to get input from those who actually use them.

"Exiting the server business" is unnecessarily ambiguous - "will no longer sell servers" would be an improvement.

'completed server systems' maybe? Something that makes it clear it is a complete computing device, not just the core component of one.

I would've gone with "prebuilt servers" or "rackmounted servers". Those are of course simplifications, but would make it a bit clearer that it's referring to specific server hardware and not servers entirely.

That would sound either like they are selling custom servers or kits, or they are selling servers in other form factors like towers which both Dell and HP have.
