Had problems with sliding in the bottom radiator with the brackets on. So, I'm going to cut the guide slots teeth off the middle brackets but leave the outers alone to secure the radiator to the case.
I also discovered I need to cut some slots to have access to the SATA connectors on the back 5.25" panel. I will probably drill some holes in the bottom and top of the HDD cage for airflow, if that doesn’t look too great, I'll cut slots out.
I got to figure out a good way to mount this thing securely without causing vibration. I also need to find a way to mount the 5.25" bay covers since the previous mounting solution is out of the question with all the cutting. I can probably add some aluminum bracing and tap some 6-32 threaded holes.
Any suggestions are greatly appreciated.
