Excerpt: There are locations on the top, side, front, rear, and bottom. I’m currently operating with four fans without any problems. This computer is using for lots of gaming, which results in excess heat, so I see the ventilation as a huge plus. If you’re looking to build a computer, I believe this case is well worth some consideration. It’s very well priced, and I feel like it’s worth a lot more than 40 dollars. I highly recommend it!
