ASUS, you have been working wonders with M-ITX lately with all those daughter boards attached and rediculous vrm on the impact. I am really looking forward to the Impact board. I was thinking though, for the ultimate compact, high-performance, portable rig, you could look into a 2011 itx (ROG? :) motherboard. I know its an absurd thought, but when you guys run out of room, you just seem to add a daughter board.
Pro's:
(1) Ultra-small form factor
(2) Its 2011
(3) More threads/cores
(4) Faster overall system performance
(5) Its portable
(6) More cpu cache
(7) More USB 3.0 ports
(8) More SATA III 6 Gbit/s ports
Con's:
(1) You lose lots of pci-e lanes
(2) No quad channel memory, unless...ASUS?
(3) More power (but you guys already have insane vrm on your impact-so it shouldn't be too much more)
Technoligical Hurdles:
(1) Massive CPU Socket
(2) More power consumption
(3) Daughter board and cpu cooler clearance
(4) Number of traces/physical connections
(5) Chipset cooling issues
(6) Keeping the board from melting
(7) Max 2011 TDP of 150W
I know its not that simple, but it would be really cool. You guys do really cool things at ASUS, and if anyone can do it, you guys can.
