Hello guys, sorry for not responding... I am busy recently so I cannot get on Tonymac. No, I haven't finished my build; all the hardware is fine, but I haven't got the Hackintosh working yet - I am stuck on the circle-slash screen. I suspect that it is because of kexts (for USB?) and USB drive (I used a USB 3.0 drive on 2.0 port).
@Vince, thanks for the kext folder! That ought to help.
@tyeh: thanks for the suggestion! But, I still obtained an i5-8400 as it is a lot easier to get. I messed around with my BIOS and it appears that I can manually tune the power the CPU recieves down should it get too hot. My rig is now running exposed with the stock cooler; I am planning to do the case mod after I get Hackintosh working. My current plan is to somehow custom-manufacture a set of heat pipe-blower fan CPU cooler along with a thin fan sucking air from the bottom cover position.
@yobro: I had decided to buy the NMVe SSD. With small files, SATA SSD should not be too different from NVMe SSD; I guess I might work more with large files, so that should help? Yes, DW1830 requires 3 antennae. I wouldn't receive it until September it though...
