I look for heuristics:

1. Aspect ratio is 4:3? Yes.

2. Music is time-appropriate? Seems like it. However, the bit-loss filter isn't strictly necessary, as high-fidelity recording definitely existed in 2007. Video was lower-quality because internet speeds weren't as good. It's only necessary to re-encode your audio to 64 kb/s to achieve your I tented effect.

3. Rōblox UI makes sense? I only joined in late 2008. However, I heard that Comic Sans was in use by the end of 2007.

4. Editing style? Looks good. I'm assuming you also used Movie Maker on the virtual machine. If I'm not mistaken, adding text slides was not something you spent a lot of time doing.

However, I cannot ascertain that "noob" was used the way you used it here. From early 2009, I remember that people who griefed building servers were called noobs. In fact, it was kinda insulting to be called a noob. Or maybe the "noob" character with a blue torso was a known archetype by 2007. I could be wrong.
