Antec P180 was one of the most popular case when it first released. It's famous for the quietness, good air flow and the clean lines. Also well known for pain in the butt with cables management and definitely not watercooling friendly especially for internal installation.
Since the birth of the orginal P180, Antec has released several revisions of P180 series. They've improved on the cable routing paths and increased its size but they are still not 100% watercooling user favourite.
I've put this case in the closet from the day I got involved with watercooling. Now it's time to come out the closet, it's deserve another chance to shine, perhaps another life.
Partical and functional with a minimal cost and all modding material will be local (no importing) sources. Improving on cable routing passages, watercooled ready and new aesthetic look. Also try not to use it's original functional designs.
