No Offense taken
I was in a similar case as you. I wanted to move on from my Cosmos S to a smaller mid tower,
I had to rule out the phantom as i did not like the door as it is not my style plus it would interfere with my fan controller.
The Silverstone as much as i have heard much of their quality it seems that "quality" is reserved for their higher up cases. ( TJ0X series).
CM 690 while it is well regarded as the best budget case for WCing I wanted to move away from CM and I personally was tired of the All front mesh look (Had an Antec 900 previously plus the Cosmos S had an all mesh kinda look in front as well.
I know the Blackhawk is a good budget case for air cooling but not so sure on the wc part wasn't on my list. (can't help you there sorry
Carbide while i know it is a capable case it has that all mesh front which was a deal breaker for me, It is a decent case and other than that I have no quarrels with it. ( I had a chance to build a computer for a client with a 600t and it was a good case to work on but just too much plastic. imo.)
The obsidian 650D is a solid case and prob the one with the most quality feel to it i would've considered it. but it was out of my price range
I chose the Arc Midi because I just fell in love with the simplicity of the looks and the versatility it has, It comes with the rubber grommets that corsair cases are known for, has the ability to fit a RX240 (double thick rad) with no modifications. and it comes with 3 black and white fin fans, has ample room in the back of the case for cable management. To me the fractal has just about all that i wanted in a case, Good WCing capability with simplistic looks that has a solid quality feel.
