I have a hp laptop and i want to use its hard drive that has windows 8.1 on it and also has documents that are really really hard to transfer , so i wanted to know if i can use that for a budget build or if its better to buy a hard drive and download a free os. I did see on other threads that it might not work but i only saw that for older os. Finally to kill two birds with one stone, does anybody know a company that makes wireless monitors so i can play pc games in a similar fashion to the ps vita's ps3(4) remote play or the nvidia shield's remote steam acsess, which means i can play games anywhere but dont need the power of my desktop in the monitor itself just a wireless connection.
