Video and photo editing not a problem at all, you will be happy with your purchase.
It is a closed looped cooling system so nothing to ever refill or manage. Also it is only on the CPU. The same cooling system also acts as a pull for air in the case, if you want more fans you will have to purchase them and install them. I have not added any additional fans and my system runs very cool even when doing gaming for hours on end.
You can have up to 4 SSD drives, it has 2 easy to access SSD's on the bottom of the case which you can easily see through the glass. It also has room for 2 more SSD behind the right panel.
