[coreboot] Beginner mobo..which of them?

[Marcello Stanisci]

Hi, and thanks for welcoming me in this ml.
I would like to buy a motherboard for build a new computer
and at the same time for study how coreboot works.
I'm looking for a fully (coreboot) supported mobo with a very simple
architecture and well documented.. In a few words: suitable for a first approach.

Can anyone help me? Which models are ok?
