The profile picture from the account, the screenshots of the account being logged into, the video that was leaked to Fox News witch matches the account profile picture, the all come from the laptop leak. And yes, the laptop, on some level, appears to be real and Hunter Biden is that stupid. The laptop had lots of personal information on it. The account was also created before the media frenzy.

New York Times acknowledging the veracity of the Hunter Biden laptop leak with a seperate investigation

People familiar with the investigation said prosecutors had examined emails between Mr. Biden, Mr. Archer and others about Burisma and other foreign business activity. Those emails were obtained by The New York Times from a cache of files that appears to have come from a laptop abandoned by Mr. Biden in a Delaware repair shop. The email and others in the cache were authenticated by people familiar with them and with the investigation.

While I agree with you on the stuff about incest or pedophilia likely being Qanon conspiracies, the laptop leak, and the files and information associated with it, appear to be real and match evidence used federal investigations, even if Giuliani screwed up the handling of the evidence.
