Verdict
Antec P20C
7.5 / 10 Expert Rating
The cheapest genuinely good mesh airflow case in our catalog, no meaningful corners cut for the price.
Lian Li O11 Vision Compact
8 / 10 Expert Rating
A tighter, cheaper way into the O11 look without the EVO's bulk, as long as you're fine buying your own fans.
