This would be a good time for a similar project with todays hardware from gigabyte with back and forward compabillity for thunderbolt and all over the same highclass specs. The way it looks I can not se a mac desktop in the close future or any thing you can put gear inside like graphicscards, soundcards etc yourself. So it may be the last chance if apple decides to take things in a direction where their future os will not run on pc hardware.
A new motherboard project like this with todays speced hardware is on my wish list. I realize it is a really big thing so I am just hoping here and I cannot contribute myself with much more than a promise to buy at least two motherboards.
So I hope the group of people that made the motherboards we already got to become reality, feel the love from the users. I am not alone I know that cause its not possible to not have had good use of and fun with this motherboard and as I understand most of them still work very good. So it would suck really hard if anything at all happens that messes with our chances that it will happen again and we get a new motherboard like this.
