Back again with another build update!
I'm moved into my university accommodation now, so I had a chance to take a picture of the cable management at the back of the pc when I did the upgrades (included in post). It was better before I got the cablemod cables with the new PSU, but thats as good as I could get it without disturbing the already okay(ish) cable management job I'd done.
So the first thing I've done is get a new PSU, ready for the 30-series RTX cards. I went with the recommended 750 Watts of power, to save me money and because its good enough to run the 3080 anyway. I got the RM750X White Edition PSU, to complement the system (of course) and paired it with some Cablemod Pro series white braided cables.
The cablemod cables are awesome and okay to work with; the only thing I wish is that the 24-Pin atx cable was longer so I could route it better at the back of the case. The cable combs are like no other though, they work super well and look the part too.
The third thing I got was another 16GB set of matching TeamGroup memory, as I'm doing CAD as part of my course, which means large assembly and part files, coupled with some simulation later on in the degree. Having 32GB should help with all that gubbins.
This will likely be the last update for a while as the waiting time for an RTX 3080 in the UK is pretty big at the moment. Overclockers said that if I preorded now I'd be waiting till January of 2021 to get it, if not later. I'll wait out the stock debaucle and stick with the GTX 970 for as long as I can. It still works and hopefully will for the forseebale future (touch wood).
Thanks for all the kind comments on the build, I'm glad some people find it as pretty as I do <3
