FIrst thing the cops would do is establish you were the only person who used the PC so they could blame everything on you. (Hard question to answer - if you say someone else uses it they'll want to know who)
They'll spend months going through every post you've ever made, make notes of it all and that evidence can be used in court. Probably be a lot of work for them so what they'll probably do is use your posts as blackmail - either plead guilty to everything we want to charge you with or we take you to court on everything you've said in your posts.
