I added eight rows of intake holes, originally it had only three.
The case comes with a 120mm exhaust fan. I moved the original 120mm fan to the front of case and mounted a BIX on the inside of case rear. An L1A Panaflo exhaust fan was stud mounted to the BIX on the rear of case. It's a snug fit but it clears the water block on the Iwill XP333 R motherboard.
A Via Aqua 1300 is next to the drive carriage. This case is real quiet.
