I'm currently experimenting with putting my MT 4790 system into a Phanteks P300 black ATX case. I've had it in a white mATX case by Darkflash for over a year now. Phanteks also offers a P300A which has a fine mesh front for more front to back airflow. Good idea if you will also using this for PC gaming in Windows. The P300 is selling for $57.99 on Amazon.com as of today. Mesh version is a few dollars more.

I'm upgrading the PSU to a 650W Seasonic gold rated model. Also trying to clean up the cable clutter too. I've not purchased the above mentioned sleeved (black) 5 pin to 4 pin adapters but I may do that just to get rid of the multicolored cables you'll see in these pics.

Here you can see how much nicer/cleaner it looks than in the stock Dell case. Dell gave you a solid side panel for a good reason. To hide their cable clutter and multi-colored wire chaos.

Here's how the back looks with the bottom mounted Seasonic PSU and Broadcom BCM94360CD card installed. The Dell OEM mATX case is the same width but a couple inches shorter than the Phanteks P300. The steel looks so much better when painted black.

Here's those gaudy yellow, red, blue and black fan header cables that kind of ruin the look. I don't need to swap the CPU cooler for a CM i71c but I'm considering it since this case has a glass side panel. The green mobo and black case interior really works quite well in terms of aesthetics.

If you can also avoid buying a MT with the multi-colored rear I/O panel, that helps make your build look much better. I got this solid black version with my MT and it goes well with any all black case when you do a case swap as I'm doing.

If you want to adapt the front I/O (USB, headphone/mic jacks) and the power switch and LEDs this case gives you more than enough room to do that with no obstructions as you may have in a micro ATX case.

You definitely don't need this multi-colored I/O shield that they also used on the 7010/9010 models. It's supposed to help you identify where the ports are. Really Dell ? It would be much more useful to clearly identify which USB ports are 2.0 and which are 3.0. The tiny SS labels are difficult to see. The blue and turquoise VGA and Serial ports are of no use to us as hackintoshers. We don't need any help finding those. I'm also not using any PS2 peripherals but I know that some gamers still use them.

Help please. I just reinstalled Mojave on my 9020. It booted off the USB installer (after using the 2.0 slot) with the OC files (from this thread) in the USB's EFI. It showed as an option in the Dell UEFI boot list. After normal installation on an internal SSD, I copied the files from the USB EFI to the SSD EFI, erasing the APPLE directory in the EFI folder there. I erased NVRAM. I can boot from an old Clover EFI that I had copied onto the EFI partition of a non-system internal HD storage disk, and boot into the new installation if I pick the Clover EFI.

When I try to boot from OC on the internal SSD's EFI, I get this error:
OCSB: No suitable signature - Security Violation
OCB: Apple Secure Boot prohibits this boot entry, enforcing!
OCB: LoadImage failed - Security Violation


Is this a permissions error, or something else?

Look at Misc -> Security -> SecureBootModel in your OC config.plist. What is that set to ?
It is set to Default. However, I saw on another thread that @pastrychef recommended reinstalling the OS from the Recovery partition over the existing installation. I did that, and it seems to be working. I disconnected the drive with the Clover EFI just to be sure, and it booted fine. I still haven't done anything with the AppleID, or UUID.

Big question: I just used the OC folder that you posted here (thanks!), without any configuration on my part at all. Do I need to update it to the latest version of OC, and configure everything? Or can I just use it as is?

If you were already using iMac 15,1 you can copy/paste your board serial, system serial # and SMUUID into the new OC config.plist. If you were using 14,2 then it's best to generate and test new ones. The ROM is the same no matter what. Use GenSMBIOS and follow the video guide for that. Once you have all your serials etc. use a plist editor like PlistEditPro or ProperTree and paste in the numbers. Keep the OC version at OC 0.6.9 for now. Other than that it should just work. I'm wondering whether you still have kexts in /L/E from the Mojave install ? Definitely check that to make sure.

Computer Warehouse, a Newegg 3rd party seller has new 9020 MT motherboards on sale for $59.99

There are only 3 in stock. These are new and not refurbs pulled from a used Dell machine. Remember that these are server/workstation boards that are extremely well built. Dell also uses them in their T1700 workstations that use Xeon processors. The BIOS was updated in July 2019 and they work great as a hackintosh.

https://www.newegg.com/p/1B4-0016-03WM8?Item=9SIA3ANAJ81011

A good idea if you want a backup motherboard for your MT or just want to build one in your own case from scratch. When you look at the cost and scarcity of Haswell motherboards that work as a hackintosh, it shows you just how good a deal these are. Remember if you start from scratch you may need a few adapters and a temperature sensor for it to work in your own case. https://www.amazon.com/gp/product/B00T10QJLY/?tag=tonymacx86com-20

The harbin repairs front panel I/O and power switch adapters will cost you $24.99 on Ebay. Link in Buyer's Guide. If you use your own ATX PSU here's the 24 to 8 pin adapter: https://www.newegg.com/p/2MV-00KA-00002?

A used GA-Z97X-UD5H on Ebay costs about $160 plus shipping and you have no warranty on it. Even if you buy all three adapters and temp sensor for the 9020 MT board, the total cost is still about $70 less than the GA-Z97X board. That's money you can put toward a new case for the build.

Yes, see the revised step number one of the guide.
I've been successfully install Mojave on my 7020,FYI I came from Clover user and still not quite familiar how to setting/setup OC configuration.
Right now I'm facing my LAN is not recognized. Should I use Kext Utility to install IntelMausi.kext? I noticed that in OC EFI folder under kexts folder already has IntelMausi.kext.

Please help.

Did you do a clean install of Mojave or just replace the Clover EFI folder with an OC folder ?

No, don't install any kexts into /L/E with Kext Utility. All kexts go only in the EFI folder on the EFI partition. That way you can easily upgrade to Catalina or Big Sur later on. You don't want to have duplicate kexts either. That causes problems.

clean install as you instructed in guide, then copy OC EFI folder as you'd attached into new EFI to boot direct from my HD
