In French reviews on LDLC, Ronan L praises the tool-free removable parts, cable clips and cable management. Kevin N says he hesitated to switch to a glass case but airflow is surprisingly good, with his GPU running 10–12 °C cooler than in his previous case using his own Lian Li fans; he had to sand the GPU bracket slightly because it hit the motherboard. CamilleM notes the 420 mm radiator bracket and GPU support are included. IgorS, who bought the white model, says the glass restricts natural airflow and good cooling is essential for powerful systems.
