Should be good, video editors can rely on the GPU so that low tier CPU will not be much of a hinderance, frankly it's not a bad price for a pre-built in this climate of GPU shortages, I'd go for it. This is a good 1080p gaming rig and for video editing you can use software like hitfilm or davinci if you don't know which one you plan to use yet. Those can utilize the GPU to speed up rendering times.
You may need to add a larger secondary storage drive if you plan to record and edit gameplay videos, they can pile up really quick. A simple 2TB storage should be enough.
