Part one of the series, the Economy end of the spectrum, Sharkoon offers quite the chassis. A completely universal drive bay arrangement, tool-less capabilities, and wire management, all at a reasonable asking price. I know it isn't huge, but the chassis is also all black, inside and out. I know most DIY'ers tend to grab whatever, and paint it themselves, or add their own wire management with a Dremmel. Sharkoon is leaps ahead of you here. Not only do they do the work for you, they aren't asking top dollar to do so.
The chassis, while light in weight, is structurally sound. I would have no issues using it or advising you to either. The performance of the chassis is limited in what I can award it. While it is simple to navigate, the lack of fans doesn't make it a furnace inside by any means, but does hurt what the case can potentially do. While the Rebel9 PE isn't currently in stock from what I can tell, the pricing that Sharkoon has set makes it a reasonable choice to start your build in. While Sharkoon uses the term Economy in describing this chassis, I think that naming is wrong. This chassis offers features that most mainstream mid towers offer. It should be the Rebel9 "Fan-less Edition" in my eyes. Economy makes me think cheap and poor quality, which this case is neither.
If you have a spare $60 hanging around, this case is a good start to a LAN rig, a HTPC build, or even the everyday surfing and e-mail family rig. It is an attractive looking chassis, and the Rebel9 Pro Economy offers things unheard of in other "Economy" cases. Most cases I see in this category are around $40 and are what I refer to as "easy bake ovens" as there is no ventilation, and limited air flow will kill a PC as fast as anything else. Sharkoons MSRP of just over $56 USD makes this a reasonable choice for the options it offers, but realistically, fans aren't cheap, and unless you already have them on hand, you can spend in excess of $100 pretty quick for the case and fans. At that point you are in the league of the Cooler Master Snipers and smaller HAF. Any of you who have seen these know they offer similar features and superb airflow, and that's a hard price level to compete on.
