Hey, I'm thinking I should get a longer plug cable for my PC (NZXT H500 case), as I've been using three cheap Poundland extension leads so far (like so https://images.hotukdeals.com/threads/thread_large/default/1471832_1.jpg) ,and I'd like to avoid any potential issues just in case and have it actually plugged into the wall. Complete noob here, will any generic cable do or will I need a specific kind?
