I built this PC to take the place of an iMac that I was using previously. I use it both as an everyday computer and primarily gaming. I was super lucky to have some friends over to help with the build and hangout while I installed everything. We didn't really run into too many problems. The GPU does extend into the HDD bay area but not enough that it looks bad though it was a pain to install. The only issue we really had was after we flipped the switch on the Motherboard for the close liquid cooler setting we couldn't find where to change it in the BIOS. As a result it kept giving us a CPU fan error in BIOS until we found it. This is a case where you are going to need to have your cable management figured out before you start your build just as a heads up to others.
