Thinking about upgrading soon, would like some thoughts on this build vs my current one.

So the first image should be the specs of my current pc, I got it built by CLX in 2022 (I just took a quick screenshot of the receipt of the parts list from my email)

Second Image should be my Potential upgrade within the next 6 months to a year from now, Here is the link btw for anyone curious - https://pcpartpicker.com/list/vgfTh7

First off, I'll obviously be gaming on it, I mainly play Ark Survival Ascended and its by far the most demanding game I play.
Secondly, I'd like to run some of my own servers for the game, for me and my friends mainly, 1 ark server uses about 10 GB per map
I'm also thinking about doubling my Ram in the future, same exact ram as the one in the PCPP picture, would end up with 192 GB.

So I'm wondering if there are any major problems with this build that PCPartPicker isn't picking up on that some people here may know of.

I can currently think of 2 that I feel like might not work.
The CPU cooler I feel like might not fit, if it does the plan is to mount it to the top of the PC
The GPU seems like it may not fit either. If it doesn't I'm trying to stick with a 16 GB card at the very least

Also I'm trying to do a smaller MicroATX case because i don't wanna deal with another giant case like what I have right now lol

Also thinking about attempting to build it myself as well, I'd like to try but as I'm sure everyone here has been told before, I'm terrified of breaking anything lol, I do know its cheaper to do it myself as well so there's that to incentivize me.

The last thing I'll mention is that the colour scheme is White with a lighter Green RGB if I can. Currently I have Black with Red RGB and I have certainly grown out of this colour scheme lol.

Thanks a ton for reading!
