For anyone interested in an alternative with removable wifi cards besides the Gigabyte Brix try this little baby.
I just picked up a MSI Cubi 004 i3 5005u Broadwell at Frys over the weekend. It has a removeable wifi/Bluetooth card. I paid $199 US and there's a $50 rebate in the form of a credit card. $149, $20 for msata 64gb, $35 for the wifi, and $45 for 8gb ddrl 3 1600 MHz. So for about $250 I've got a great little multimedia center. This is not a Nuke, but it has the same platform except for the soldered wifi card. The only drawback is the legacy bios, however once installed I'm running Sierra Beta 5 no problems, and I got a bonus, it comes with HD 5500 graphics, however mine reads and has metal support for Intel Iris Pro 6100 graphics. I added the HD 5500 sdst to clover acpi patches folder and I used the 16160002 Fake ID. I was getting it early on and thought it was cosmetic until I added the sdst to clover then it lit up with support. Tuesday my Broadcom wifi card will be here so I'll report back on how wifi works soon. It's strange but I do have Bluetooth support on the Intel wifi card.
These are tough nuts to crack when loading a fresh install, it was very gratifying once I got it to autoboot without any -x, no caches, -v boot arguments. Later tonight I will post my config plist for anyone interested in trying one out. My system definition is MacBook Air 7.2 however it natively defines itself in clover bootloader as an iMac 15.1. You need to use legacy boot mode to get it to run the install. The only drawback is the weak bios options, it's up and running and passing Uningine benchmarks. Valley extreme HD @ 4 fps, woohoo! Scored a 150, yeah!
