So, I am building a new machine, and I decided to forsake my old Q500 and move for something a little more... portable, I decided upon a PC Power & Cooling Midtower with the hard drive rack add on, anyone own one of these cases? They have 4 5 1/4" externals, 2 3.5" externals, and 2 3.5" internals (after drive cage addon). I'm trying to figure out how modable these casees are, I figure I will add handles, a blowhole or two, and maybe a case window. So, has anyone played around with these? Any sharp edges? Thanks in advance.
