I think an hour is optimistic.
I rarely build PCs and I think my last one took way over an hour.
Watch YouTube vids. Lots.
Plan ahead carefully.
Which wires are you plugging in where?
How do they get there neatly?
Which way does the CPU go?
Direction of the cooler fan?
Best slots for ram?
How you set them.
The correct slot for the GPU.
Sure the GPU fits the case on top of the motherboard?
Take it really slow.
