Antec has followed the motto 'If it's not broke, don't fix it', for some
time now with their Performance One series of cases. The core function and style
of the case is retained but they have made a few tweaks to improve on it. There
is greater airflow with the improved vents in the front door and drive bay
covers. As with its other siblings, the P183 is made of quality materials and is
therefore quite sturdy and strong.
