Well, I am making progress on the computer. The attached photo shows all 256 Gig of the memory in place, the 5 spinning drives in the front for the RAID5 and the arrows are pointing to the two V-NAND SSD 2 Gigabyte 970 EVOPlusNVMe M.2 Socket 3 (dang what a long ridiculous long name) solid state drives. There is space for a third M.2 drive that I may add later. I will use one as the boot drive, and the other as the "work" drive. Once a project is done, it will get moved to the RAID. The bottom arrow points to the one that is installed, the other one is uncovered for a few minutes more.
I still have to get the DVD burner and the USB and multi memory card reader in the front. Add in the video card, and lots of other cables and thermal sensors. There is a little add on card that comes with the motherboard for fan control, and I don't know if I will add in the wireless WiFi or not. With the computer 5 feet from the router, the Cat 6 cable will bring in all the network speed it can handle.
The packaging they ship the parts in is nuts. They have the motherboard in a box that I bet cost 10 bucks or more. Very fancy, and the power supply has a neat little bag for the cables. The hard drives were the opposite, just a big bubble wrap around each drive and nothing else. Same for the DVD burner, just bare.
The motherboard does come with one gizmo that I will not install. It has a little bracket thing that glues to the top of the monitor and adds a video camera, microphone, and audio controller. It might be great for gaming, but it ain't going on my computer.
The CPU cooler is a real mousetrap contraption. It looks well engineered, and it has four little rubber mounts for vibration reduction and to make it quieter. Then a spring gizmo that hold it tight.
The M.2 hard drives fit under a metal panel, with double sided tape to hold it tight, and transfer heat. The one on top still needs to have the tape stuck on, and be put in position, and the screws tightened.
Once I get this computer up and stable and software installed, I will transfer the software from my current machine to this new one. Then add the video card in my current computer to the big machine, and make my old computer nothing but a RAID 5 computer.
