Design Features
PSU FittingNow one of the major problems with the last version of the ATCS 200 was the way in which you fitted your psu, frankly it was a pain. You had to first remove the top panel then slide it in from above. It was a tight fit and some psu's didnt like it. To further compound this with dual fan PSU's some of the airflow was blocked by the PSU cage. Thankfully all this has now gone, PSU fitment is now much like the ATCS 210 , first a plate is removed from the back then you slide in the psu and replace the plate attaching the psu to it. This is much less painless, and now there is no blocking of the bottom fan, another big improvement.
Cooling
Now the cooling on this case is very very good it has been perfectly setup with the dual front intake fans. The rear fan now has been changed with better airflow due to less blockage.
The top fan has been altered now from the previous version it is much more similar to the way the front fan is implemented. It has a mesh square in which the fans is placed and then this mesh is attached to the case.
This improves the look of the top of the case no end.
All the fans are YS-tech's as with most Coolermaster cases, one change is that now the rear fan is a three pin version which means you can plug it into the motherboard and not have wires running all over the case. All the other fans a four pin molex connections as normal. The fans provide a good amount of airflow while not being too noisy. Overall the cooling is a tiny bit better than the previous version I noticed about a 1-2 degree drop, but its difficult to be precise due to changing abient temperatures
