Spent all weekend assembling this Core One. It probably took 14 hours in total. 12 hours to build and 2 hours to troubleshoot issues. Broke some parts made some mistakes but I finished the build.

Thank you!
I bought the printer after the core one L news. The core one L is way more expensive (it's almost double the price) so I went with the core one.
Haha. No.
I wanted to build the printer because like you said it helps you understand how printers work and this was my first printer so I thought it was a good idea. It also helps if you ever need to service the thing since you get a good idea of where everything is and what each part does. I also thought it might be fun because some people likened the experience go building a PC and I enjoy building PCs.
Unfortunately I have to say building this 3D printer was nothing like building a PC. It was way more challenging in my opinion. I was also very nervous the entire time because you don't get to find out if the thing actually works until the very end. My heart sunk when I first turned the thing on and the Z axis was just completely not working. Thankfully the issue was resolved after talking with support. Definitely have to agree that Prusa support is amazing.
Also, I found assembly to take way too long. It's my first printer so that might have been why it took 12 hours. I heard it took some people only 7 or 8 hours. I think I would draw the line at 5 to 6 hours for 3D printer assembly if I were to assembly another one unless the printer allowed you to test during assembly.
