The basics on most Intel or AMD motherboards will work 'out of the box'. CPU support, memory, etc. should never give you issues. Sound and networking chips can be dodgy with linux, but generally they are fine as well.
The only time you really have issues with linux and motherboard parts is from stupid addon SATA controllers, wireless network adapters, etc..

Brand will make zero difference. Intel works as well as AMD does (though I get tend to get AMD CPUs for various reasons).
That translates as "buy big branded hardware from companies that have paid canonical to get 'certified'". While its not as bad as it was in the past, the 'ubuntu certified hardware list' is still pretty much a joke.....
