Four PC cases compared, from the QUBE 540 to the Define 7, with the trade-offs of each named.
By The PC Journal editorial team
11 min read4 products evaluated
E-ATX gaming cases combine big-board support with glass and fans. Every pick supports E-ATX, ordered by GPU clearance.
Our comparison rests on published figures for max GPU length, largest radiator and fans included; where a maker leaves out max GPU length, we say so, and no figure here comes from our own testing.
