Got a fractal design define XL case a year or so ago, still love it. Best design and quality of case I've seen in years. So anyone looking at Fractal cases, ya, they're worth it.
Yes, it is new. You may have the ARC MINI (the R2 version comes with a window) but so far the ARC MIDI R2 is only available with a tinted window. There are also other updates with the layout too. This should be cheaper than the windowed version but will probably launch at the same price, so around the £70 mark.
How about the mATX Define R4 gets a windowed version?
Seriously. I've been on the lookout for a windowed mini tower case and the Obsidian 350D seems to be the only one on the market. While the case certainly isn't bad, I would prefer a windowed version of the Define Mini because my current rig sounds like a jet plane,
