The L1.0 is our largest and most extreme computer case to date offering unprecedented watercooling support without losing sight of our established compact ethos. We believe the L1.0 offers everything the true enthusiast would expect from an E-ATX case, with room for four of the largest graphics cards available and the radiator area required to cool them effectively and quietly. Layering and forming techniques are used to give the case its distinctive sweeping lines while providing exceptional structural rigidity for its impressive magnitude.

Due to us constantly upgrading and updating our designs, some small aesthetic changes may occur.

We source our raw materials carefully choosing only high quality, recycled, European made acrylics. 
Waste material is recycled and our production process is optimised to reduce it is much as possible.

Delivery Time

Order lead time: In order to offer a wide range of designs and colours all cases are produced to order consequently our lead time has to be more relaxed than that of a distributor. Please expect between 5 and 30 days when ordering any cases, 30 working days is a worst case scenario. Smaller cases should be faster and this is something we are aiming to improve moving forwards.

CURRENT LEAD TIME: We are currently operating on a 7 day lead time.
