Well I would check, but then I'd have to climb under the table and curl into an uncomfortable position with a torch to find out (don't ask!). I'm assuming, given this is my computer, that I don't, or if I did, it relied on the CPU having the outer casing it started with, and not having had every single one of its components apart from the monitor, keyboard and mouse changed multipule times since I bought it! That, and the place I'm going to be staying in doesn't have the internet anyway. Thanks anyway though!
