This discussion never gets old to me.
I personally use or have used; Cosmos S, HAF X, and 800D to house 360 rads internally. They all have different pros and cons.
HAF X: Good airflow, great cable management. Not a lot of room for very thick rads, but they will fit, may hang over motherboard. Side window available/comes with.
Cosmos S: Good airflow depending how how you set up fans, horrible cable management. Not a lot of room for very thick rads, but they will fit, may hang over motherboard. Side window available.
800D: Mediocre airflow, good cable management. Plenty of room for thick rads. Side window comes with.
All 3 have LOTS of options as far as modding for extra rads besides the 360.
I would very much love to try out a CM ATCS840... maybe someday...Edited by Segovax - 10/14/10 at 11:14am
