Smaller is Better now that we have a range of quality offerings in both motherboards and GPUs..The fact that Case Manufacturers have finally been offering some great units that can house a fully WC'd system in a case that isn't 3ft tall and weighing 30+lbs loaded...
These would be a great chance for me to dip my toes in the SFF world again!!
Smaller has always been the goal with tech. Without ever shrinking components how would we ever post on Facebook while eating Doritos at 2AM from the comfort of our couch after a particularly rewarding round of Super Mario Cart running on our Asus powered SFF media center PC running Nintendo emulation to relive 16-bit glory?
Smaller is better because my GF is tiny and I love the shit out of her.
Also because you can put a gaming rig in places like a TV setup or have 4 small pcs in the space of two large ones.
More pcs, less space, more lan parties.
Smaller is better because it looks better and it means I have more flexibility in where the case goes, leaving more room for things like speakers and a printer.
I built my wife a new system around a mATX that sets on a bookshelf in the den and she loves it. This would let me experiment with the ITX form factor and see if I need anything bigger. With 4 PCs in the house, only one has more than a single video card.
