CONCLUSION

   If you are like me and have been waiting patiently for the successor to the Obsidian 800D then you will probably find a few flaws with the 900D. Sure it's a very high quality tower and due to its huge size it has plenty of space for mainboards (up to HTPX in size), fans (15), radiators (5), 2.5"/3.5" drives (9), 5.25" drives (4) and it even has room for two power supply units but if you really take a close look in its interior it won't take long for you to see that Corsair could had made use of some "empty" spots for numerous other things (such as SSD mounting spots, tube reservoirs and more) so i don't know why they chose not to. An extra 5.25" optical drive bay would also be a very good thing to have since even midi towers have 3 so the flagship of the Obsidian line should have at least 5. However i do consider the tool-less design as a plus (although the placement of the PCI expansion slots makes it very hard to secure them in place even with thumbscrews) and i particularly liked the left and right side panels which can be removed at the press of a button while thanks to all of the air-filters used it's a safe bet than you won't have to worry about dust. Overall the new Obsidian 900D Super Tower is a real goliath amongst PC Cases and that alone will go a long way for modders, enthusiasts and overclockers.

   Just like the Obsidian 800D no one really expected for the Obsidian 900D to be cheap and it's far from that since it currently retails for around USD350 inside the USA and for 324.90Euros inside the EU (Caseking.de). That being said we know it's not cheap but for people who can really put all of this space to good use there's simply nothing better available currently in the sub USD400/400Euros domain. Bottom line Corsair has launched one of the best HPTX compatible PC cases in the market and although yes it's far from perfect in the end the old saying by Desiderius Erasmus "In the kingdom of the blind, the one-eyed man is king" is a perfect match here and since in the market there aren’t any better PC Cases at around the same price point currently (the Cosmos II looks better but has less interior space) the Obsidian 900D gets our Platinum Award.
