The 15th machine I've built. Goes to a friend's friend.
I have left provisions for the owner to add a second GTX 970 down the road. Hence the Z97 board and 750W PSU, otherwise they are not necessary for the time being.
Notes: 1. Didn't opt to use the case's fan controller, all fans are connected and controlled by the motherboard. 2. Datasheet states the MSI GTX 970 is 7mm longer than the max clearance of the Arc Mini with drive bays attached, but in reality there's actually about 10mm of extra space left over. So the card actually fit pretty nicely. Just wanted to throw this information out there for others who want to use these parts.
