Jonsbo, who have recently reentered the American market, have launched their latest PC case, which sees a departure from the norm (in a seen-before sort of way, though). The TR03 is a triangular case, eschewing the usual boxy design of 90% of the market. The TR03 is made of aluminium, for the outside and steel on the innards to achieve structural integrity, and features tempered glass side panels for showing off your hardware - like any enthusiast case true to its name should.

The TR03 supports radiators up to 360 mm, CPU coolers up to 175 mm, PSUs up to 185 mm and graphics cards up to 460 mm, so you known you won't have to make forced decisions regarding your hardware configuration on account of this case. The interior of the case is modular, and can be rearranged in a number of ways to display your hardware vertically or horizontally, and pre-designed mounts for your custom water tank mean you won't have to worry about your hardware's integrity. It supports up to ATX motherboards, has mounts for 3x 2.5" SSD + 3x 3.5" HDD or 5x 2.5" SSDs. It also features supports for up to ten fans. No word on pricing at time of writing, but you should expect this case to be in the upper echelon of pricing for the company.
 
This is such a strange design that I actually like it. 
 

I have to agree that I kind of like these cases. It looks different but not so radical that it doesn't feel fit into a room.

It reminds me of the Alienware Area 51 case.

It probably is.

Love the concept but I'm just not convinced on airflow.
