First question I'd ask is, "Why"? What does the Z170-E motherboard give you that your current motherboard does not? Given your current system is a pre-built system, a transfer of the Windows OS license may not work which means in addition to the new motherboard, you would need to purchase a new Windows 10 license.
And as far as the Windows install is concerned, if you're swapping motherboards, you'd always want a clean install of Windows and any applications you would install. Otherwise, you're just asking for complications/conflicts/slow-downs.

Hi wolf thanks for the reply the reason being that the z170 e motherboard allows me to have sli and or more expansion cards which would help me future proof it or at least for a good while more also i dont mind having to buy a windows 10 key thats completely fine also reason being that i would want to switch motherboards is because im not sure if my motherboard currently has enough fan headers for the case fans of my new case im moving my pre built to a new case because my GPU when gaming is always at 90-92 and i have replaced the thermal paste twice both in the last month and have cleaned out the case every 2 -4 weeks which i feel would be because of how much limited air flow is in the pre built case also the motherboard allows me to have 4 RAM sticks of dd4 which if i wanted to upgrade from the 16 i would be able to as i only have 2 RAM slots in my current pre built thanks for the help!

It seems you wanna get a new mobo for reasons you should not.
1. Adding more RAM could lead to compatibility issues. If the day comes that you will need more than 16 GB RAM, you should buy a new kit of 2x16 GB instead as they come from same batch and have been tested to work together.
Also if this is for gaming, when the day come that games will need more than 16 GB you will need a new system anyway. Games hardly needs more than 8 GB still.
2. SLI is not worth it, and it would be better to get a new single card than messing with SLI. Not to say that your current PSU will probably not be enough for SLI. They doesn't even state the PSU model installed, which is probably because it is a cheap crap unit.
3. Needs more PCIe slots? What exactly do you need to install?
Seems you wanna get a new mobo for possible future upgrades that you are not even sure you will get.
Tell you what, don't buy anything until you need it, It's very possible when you actually need it, you will be better of with a new system, faster CPU and such and then you are stuck with an old platform that doesn't support new CPUs.
