i've been through a fair few cases in my time including but not limited to Chieftec Dragon, Globalwin, bunch of Lian Li's, Corsairs, Mountainmods etc. My current rigs have been overhauled and am using a Jonsbo UMX4 and a Lian Li 011D Mini. Should money be no object including individual parts to build it in, i would switch to a Caselabs SMA8, but money being of concern, i am happy with what i have at the moment.
There's always new and exciting cases being released so i have yet to find a firm favourite.
In terms of part 2, only cases i am aware of and actually used are Mountainmods, Lian Li and Caselabs... I'm sure there are plenty others but since i have not used any (none of those listed) in a build, i can't say which
