The general noise level of the Obsidian 650D is perfectly acceptable, even when running the fans on maximum setting and as with the other cases in the range the Obsidian 650D has excellent air flow throughout the case. The two large 200mm fans provided with the case are extremely effective and there is plenty of room for customisation of the top fan which can be replaced by two smaller fans or switched to a water cooling system.
At £135/$210 the Obsidian 650D is the cheapest case in the Obsidian range and although the larger cases in the range offer the benefits of full-tower design the Obsidian 650D is certainly well equipped for a mid-range case and at this price point is a very attractive option for anyone looking for a new mid-tower case.
Summary
Excellent build quality, great airflow, low noise, a spacious design and an ideal price point means the 650D is a great addition to Corsairs Obsidian range.
