Hey, I'll go on the record as a huge fan of Parts Express to say that the case listed by them is an absolulte POS compared to the JWRace version. First off Punching the correct holes in the right places and predrilling for the mounting posts and transformer mechanically makes this more expensive case worth the extra cash. The build support and parts list also go along way towards making this somewhat intimidating task much more do able as well.
JWRace makes a solid well laid out case for not a lot of funds, I tried to do it my self, and after floundering for a bit 190 bucks seemed like the bargain of a lifetime!
