I’m in the process of building dad a new pc. I’m using a gigabyte B250M-DS3H board and I’m air cooling. I’m using his existing Corsair non-modular PSU. Just using the intel gpu. He has a DVD drive, 2 HDDs and an SSD. I have an Aerocool CS100 case spare but the problem is that it’s pretty small and the non modular psu makes it a squeeze to get everything in without seriously compromising airflow. So I’m looking for something a bit more suitable hopefully around the £60 mark. The only other criteria is that it must be no more than 41cm tall so it can fit under his shelf. Any recommendations?
