I thought it looked familiar. Same dimensions as the Define R6. Same front panel connectors as the Define R6. Same pop-off top as the Define R6. Looks like the Define R6 with a permanent optional "open" configuration setup (see Define R6 manual for details). Differences on the S2 that are noticeable: 1) Less HDD cages overall. 2) 3 HDD mountable drive cages on the back side of the tray can be used with HDDs or SSDs. I could only get one of those mounted on my Define R6 and it only mounts in a vertical orientation. The HDD/SSD mount availability with the on the S2 is definitely a refinement over the R6, if you use the "open" configuration of the R6. If you need more HDD drive mounts, the R6 is still king. One thing Fractal can still improve upon: Include more SSD trays. In addition to the SSD drive tray mount points on the backside of the motherboard tray, there are two more SSD mount points above the power supply in the main section of the case (just like the Define R6!). Whether you get the S2 or the R6, you only get two SSD drive trays and Fractal doesn't sell these separately if you want more of them (I waited one month for this answer from the Fractal sales team). Why not throw in two more SSD trays, Fractal??? What if you're the type of person that wants their RGB SSDs showing up front with your main components? You have arguably the best cases available. Just include two more SSD drive trays! Geez!
