The arrival of the rumoured 4700g is gonna change a few things. Now it's possible to do a powerful 16 thread no gpu build and that too with only upto a 150w power supply. Apu cases are going to get more popular at the expense of cases such as L5 which cater to lp gpu + strong cpu audience. I hope you take this into consideration for future designs.
Debatable. A lot of APU cases are designed around using external bricks, whereas with no lp GPU you can mount a variety of PSU inside the L5, and still get cooler clearance to run the L12S. Lots of APU cases force you onto small coolers.
