If you keep the Z170/Z270 platform, the best route you have for upgrades is to an i7 7700k which, while an upgrade over your i5's, is a few years old at this point. For storage, you can keep the 2TB HDD for mass storage and get SSD's for your OS. Or, you can completely switch over to an all SSD system; one SSD for your OS and games OR an SSD for your OS only and another one for mass storage. PSU is honestly fine up to a point. 1070 is still decently powerful but if you are upgrading you might as well upgrade completely. RAM is a definite upgrade, as well as CPU cooler. Honestly, it all depends on your budgets and whether you want to stick at 1080p, or 1440p. Either way, I am attaching a couple of systems for 1440p with new CPU's, mobo's, RAMs and either
(a) keeping your HDD and adding an SSD or
(b) one SSD for OS and Mass storage or
(c) one SSD for OS and another for storage. I will be providing both Ryzen and Intel systems.
I will be assuming around an $1500 budget for each system. I will be assuming RGB and looks are not too much of a factor.
1440p - Intel - Option (a):

[I went with the 3700x over the 3800x as the performance difference does not justify a nearly $60 difference]
1440p - Intel - Option (b): [Do note for Option (b) builds it will be a 2 TB SSD to match your 2 TB HDD. But this will warrant a sacrifice in other departments.]

[This build could accommodate a 512 GB SSD and a 1TB SSD instead of a regular 256GB SSD]
Points to Note:
- If you want to stick with 1080p, the GPUs can be taken down a notch to RTX 2060's or 2060 Supers' or you can even stick with your 1070s.
- You will need Windows for these new Systems as there will be new motherboards and CPU's, so install windows using a USB and get an authentication key online.
- You will have noticed the Ryzen builds being cheaper by a margin. If I were you and looking for bang for buck, Ryzen would be the way to. But Intel is still slightly better at gaming than Ryzen is but honestly, Ryzen would be the way to go.
