Solaris HW compatibility list

I'm picking HW for my cheap Solaris server and am wondering if there is a decent list of HW compatible with the Solaris OS.

The best I could find is this: OTN - Oracle Solaris 11 11/11: Hardware Compatibility List, but it surprises me that only a single motherboard is listed.

I am searching for a cheap and tiny motherboard plus CPU with passive cooling. I would appreciate any hints on concrete HW as well.

Thanks in advance!

I suspect it is because Solaris 11 is not aimed at enthusiasts who build their own systems.
