    Reviewed in Italy on August 29, 2019
    Caratteristiche generali:
    +Il case che mi è arrivato è senza slot per lettore dvd/ ODD 5.25", ottimo perché è quello che volevo
    +Il case di estetica mi ha davvero catturato, il montaggio è semplice e l'alimentatore è nascosto. ottimo
    +Il pannello laterale è in vetro temprato ed è facile da attaccare saldamente.
    Airflow e ventole:
    +Sono incluse due ventole mediocri della coolermaster, aggiungendo altre ventole l'airflow diventa eccellente
    -Evitare le ventole da 14cm con fori da 12cm in quanto non finirebbero montate in modo simmetrico
    -Sul pannello frontale le asole sono davvero poche, con ventole da 14cm si è costretti a montare una ventola da 14cm in alto e l'atra in basso, lasciando così uno sgradevole spazio centrale tra le due ventole
