Features
There are numerous changes in this new model.
With that in mind, I will have links throughout this section to some pictures
of the PC2-650 for comparison. Let's begin with one of the most
significant changes, the front of the chassis...

Yes, the very cool
frosted circuit board design
is gone, however, the new case deviates from its all to distinctive features
of the Chenming cases, which I have always found quite unappealing.
While they did choose a much more moderate design this time around, they sure
make up for it with its new LED control panel. Like their previous
models, it features front USB, Firewire and audio jacks. The power and
reset buttons haven't changed. The reset button is still quite small and
can be hard to press, especially for those with large fingers.
Other significant changes are found on the
inside of the chassis. One major change here is the location of all the
water-cooling components.

The radiator is nicely mounting on the inside
upper section of the case just like their older models. However, the
PC3-720BK no longer has the
plastic shroud we saw with the PC2-650. Also noticeably different,
is that all water-cooled components have been moved to the top of the chassis,
including the reservoir, pump and power control board. This is certainly
a great idea, and one of the things we
complained about with the
PC2-650BK.

The drive cage has also been completely
re-designed and quite different
from the all too familiar removable drive cage design seen with the PC2-650.
It is designed for quick and easy installation of drives.

Now, one other thing I was not too thrilled with
on the PC2-650, was the LED
temperature panel. In the article, we had to
mod it to fit the overall
theme of the case. Fortunately, the new PC3-720BK features an excellent blue
LED display with many additional functions that I'll go over a bit later in
our installation section.

Another nice change Koolance opted for, was the
method of cooling the radiator. Instead of
three 80mm fans, now you have
only two large 120mm fans for quieter operation. Nice move here, as
120mm fans are significantly less noisy and provide much better airflow. The fill cap is now on the top
and the reservoir is lighted to please all you case modders out there.
We'll see it all in action a bit later as well.

Finally, no case that bares the name "Server"
isn't complete without some security features. Like their previous
model, both the side panel and front drive door can be locked with the
included keys.
