It's been 13 years since I put together a PC. Things have changed a lot but they are still the same; everything still fits in the right places except it's easier to be cleaner and make things look nice now. RGB has also taken over, but I liked the neon tubes back in the day too.
I'm glad the cases these days have hidden cable management and you can be as organized or unorganized as you want behind the scenes. Only thing different I would have done would be to do a custom watercooling setup. I've never done one before and didn't want to spend the time and energy to figure it out but it would have kept my system a lot quieter. Maybe a future project.
For those that are looking to know some of the annoyances and minor details of the setup...
Gigabyte Aorus Master Motherboard does not have the 24 pin lined up with the cable slotting of the Lian Li 011 case. You can see the curvature in my picture. The USB 3.0 plug on the motherboard also is at an inconvenient vertical location so I decided not to plug it in as I won't be using it anyway. My preference for both the 24 pin and the USB 3.0 plugs would be for them to be horizontal which would allow for less cable clutter on the visual side.
NZXT AIO water lines do bump up against the first row of RAM next to it. Only way to fix that would be to either move them further apart on the motherboard (which I can't do) or to rotate the AIO itself so the water lines are below or above the CPU.
Gigabyte 2080 Ti card I mounted vertical for esthetics and also there is sag when mounted normally into the board. Downside to mounting vertically is the GPU touches the RGB RAM covers. Technically it is the heat shield on the back of the GPU that touches the RAM covers. It is unavoidable but I don't believe it affects the RAM or GPU other than light physical scraping if you move it. Also, vertical mounting increases GPU temps for me by about 2-3°C
I don't know if Corsair or NZXT has fan controllers that can control more than 6 fans. That would be useful with all the cases that allow 6+ fans.
For case fans, why don't manufacturers make fans that spin clockwise or counterclockwise that way RGB can be facing either into the case. So if I want to do a pull configuration the RGB ring is showing when I look into the case rather than looking at the fan back plate. Maybe air flow just won't work this way for a particular reason. I'm not an airflow expert shrug
Lastly, if I turn fans all the way up on this thing, it sounds like there's an engine in the room. Not the biggest fan of that (pun intended).
I spent too much money on this machine even though I don't have enough time to spend on it. That's what happens to old gamers, haha. Nostalgia.
