Server hardware compatibility

Hello,

I am preparing technical specifications for the purchase of a new core server to work with Proxmox. Wiki says the hardware compatible is, in general, the hardware compatible with RHEL 6, but until I know Proxmox uses Debian.

Do you think I should ask for the hardware has available drivers for Debian? Or the drivers for RHEL 6 will work properly in Debian?

Maybe I'm asking the obvious...

Thank you
