I picked up this Optiplex 9020 6 or 7 months ago for my son(9 at the time) because he was interested in getting into PC gaming. I have been upgrading it here and there and i finally decided it was time to swap it into a case with better air flow, the stock case was basically an oven. If anyone is interested YES the motherboard is standard mATX layout and fit in the case perfectly. I knew going into the case swap there were 2 or 3 hurdles to deal with. First and foremost was the proprietary power button header on the motherboard, after looking at what answers the internet had for that problem I decided to pull the entire power button assembly from the Dell and make it work in the new case. It only required shaving the feet off of the back of the button housing to get it to fit and some hot glue to get it to stay in place. That method allowed me to keep the power and standby lights that glow through the power button. Up next was the front panel I/O. Again here the internet wasn't much help so i decided to go with a case that had 1 5.25" bay and build a bracket to house the I/O panel from the Dell, honestly this wasn't completely necessary as i could of just left it out and only lost front panel audio and hdd activity light, but ya know "no compromises". I am still working on a clean way to trim it out and have it usable. The one thing i may have done different would have been to use PWM fans because these upHere fans do not attach to a fan header at all so I do get a warning about no system fan when i boot the computer that i just have to press F1 to get past, so there is that one compromise i guess. All in all i am super happy with the way it came out.
