Since I think I need a new power supply, I am planning to upgrade my case, too (I have some need for an additional bay, too). My computer is an HP with a 4th gen i3, I upgraded the ram to 8gb, and the graphics card to MSI R7 240. Maybe I will upgrade the graphics card again to help support a large monitor for productivity. In a nutshell, it's a "budget" or slightly above budget computer (meaning it doesn't need a lot of cooling). I have found a couple of inexpensive computer cases but some of them support many case fans. HP shipped this computer with 1 case fan (although I realize that maybe I have "grown" into two), so I am concerned about not being able to just ignore the case fan slots as that will have a negative effect on the airflow. Is this a valid concern to have? I don't have experience with building computers and I am not going to be able to afford much downtime. Will it likely be a smooth process to move my computer to a new case?
