Is there a website that lists modern components that work with AROS properly?
If I go out and buy an i7 3600k for example which motherboards are best, I think this is really important if AROS wants to grow in popularity. People building modern super fast AROS machines based on i7 tech is the only way forward IMO.
The i7 itself wont be a problem. The problems you might have, are with SATA controllers, Graphics, Sound, Network, USB etc.
Your best chance to get a 100% supported PC, is to go into the shops and ask them to boot a AROS live CD. You can then test anything.
BTW. Network and Sound support can be easily added with cheap Add on cards.
