Lian Li O11 DYNAMIC EVO RGB

Lian Li O11 DYNAMIC EVO RGB

6.2/10verdict: good, not the best

The Lian Li O11 Dynamic Evo RGB is for builders who want a showcase PC with room for large radiators and long graphics cards. It suits people who plan custom or all-in-one liquid cooling and are happy to buy their own fans. It is a poorer fit for anyone who wants a case that arrives ready to cool a build.

Phanteks XT Pro Ultra

6.7/10verdict: good, not the best

The Phanteks XT Pro Ultra is a mid-tower for builders who want a mesh-fronted case with fans already fitted. It suits people planning a large graphics card, a tall air cooler or a 360 mm radiator. It is less suited to anyone who puts quiet running or a rigid side panel first.
