What lenovo laptop? I have a friend with the standard Razer blade and that thing is beast, and to him it was worth the money. I do think these things are a bit over priced, but I still wouldn't stop you from buying one.
Sadly DDOSing is extremely easy, however it does not usually take any personal information with it, its just a pain to fix. I can DDOS but ill never do it
Port forwarding is done through your router not minecraft. Be sure to put in your computers individual ip in your router port forwarding section and not your external ip. My ISP is comcast and im home hosting my server.
On your router there should be something related to Porttrigger/forwarding, just place your PCs (internal) ip in there and congrats u have port forwarded... I used this to host my minecraft server
Since the PS4s specs were announced id like to see Microsoft top it... A freaking 8-core processor in a console is amazing. also you can play used games on the ps4 without paying extra
