just built a budget gaming rig for a friend with that cpu, but went with the gigabyte mobo, I never worked with a micro mobo, Is it allot smaller? , how hard is it to work on with big fingers? any advantage of micro over just atx?
The M-Atx motherboard is not hard to work with. It is basically the same size of an ATX board with less expansion slots, so all the connector areas, CPU and etc are just as easy to work with. No advantages over one or the other. It is just more about size of the case which drives the need for one or the other.
The ATX motherboard you've list is nice. I would still go with the M-ATX board do to the combo sayings. You can get an idea of working with a M-ATX board by reviewing my Step-by-Step guide in my sig. I used one for that build in an Antec 300 Illusion.
