It's rather unique looking, I'll give them that.  ZALMAN announced the Z-MACHINE 500 open-frame PC case that uses curved tempered glass (which is difficult process).

The open frame PC case uses a large tempered glass panel with a curved front face. The form factor is compatible with E-ATX (up to 280 mm), ATX, MicroATX, Mini-ITX, and the pump/reservoir tank installation space for the DIY water cooling system is also prepared in advance. The chassis material is made of alumite-treated aluminum, and gimmicks such as the back wiring space, cable timer unter, and bottom cover that hides the cable from the power supply unit are mounted. By minimizing the cables peeking through the tempered glass on the left side, you can dress up the inside of the case beautifully.

The drive bay is 3.5 inch (hidden) bay x1, 2.5 inch shadow bay x1 or 2.5 inch shadow bay x2, expansion slot is 7 stages, graphics card is 400 mm in total length, power supply unit is 200 mm in depth, CPU cooler can be installed up to 210 mm in height. The cooling fan is 120mmx3 at the front (SF120: 120mm ARGB fan x3 standard), the top is 120 / 140mmx2 (SF120: 120mm ARGB fan x2 standard), and the radiator supports up to 360mm at the front and 280 / 240mm at the top. The I / O port is equipped with USB3.1 Type-Cx1, USB3.0x2, USB2.0x2, audio terminal, and an addressable RGB LED controller is also standard equipment. The external dimensions are width 280 mm, depth 630 mm, height 603 mm, and weight 10.5 kg. 

A price is to be announced.

Update: this thing is priced insanely at 1000 EUR.
