Oops, I forgot to update this thread as I was having a mare with the CPU overheating. I'll get into what happened below
Taking the fan off the G2 to install it:
Note to everyone else, remove the plastic guard before installing it on the CPU:
As embarrassing as that was, that isn't actually what stuffed me, although it probably caused my concentration to lapse.
When I did install the G2, I didn't quite line up the screws properly, so had to pick it up and reseat it. No problem, so I thought. What I truly failed to consider was the impact that had on the plastic thermal paste guard I'd put in place. I'm pretty sure the plastic was sitting right on top of the CCD, oh no!
Well, after a lot of worrying a reseat sorted that out no problem. Here's how the rest of the build went.
Hooking up the cables. GPU-less:
Oh, hello, Lian Li and 3090... I shall extract you!
Sitting in there nicely:
Now with the GPU stand that comes with the case:
I think it looks pretty good! Take that, nay-sayers
One thing to watch out for with the GPU stand is that I've scuffed the bottom of the case (where it's sitting) slightly from getting this into place, which was annoying, so do be careful with this!
