My first post here so before anything else 'Hi guys...' 
This is my proposed build - and apart from it not having an SSD (I'll add that when funds permit) does anyone have any comments? Is there anything that will give me a problem that you can see? Is there anything you would substitute without spending a lot more cash?
The proposed use for this is No Man's Sky and Star Citizen both of which have high graphics requirements
MSI Z170A Gaming M5 Intel Z170 (Socket 1151) DDR4 ATX Motherboard
Intel Core i5-6600K 3.9GHz (Skylake) Socket LGA1151 Processor
Asus GeForce GTX 970 TURBO OC 4096MB GDDR5 PCI-Express Graphics
Kingston Fury Black 16GB (2x8GB) DDR4 PC4-19200C15 2400MHz
Seagate 1TB 7200RPM SATA 6Gb/s 64MB Cache HDD
OcUK 24x DVD±RW SATA ReWriter
In-Win 703 Midi Tower - Black / Red
Akasa AK-CC4009EP01 Venom Pico Compact CPU Cooler
Pure Power L8 600W '80 Plus Bronze' Power Supply
Many thanks y'all
