[Closed] Best Laptop for £500ish?

My laptop is pretty much dieing, so I need to get a new one. Things it needs to be able to do are:

Internet surfing
Run at a decent speed for MS Office / wireless
Have some graphics / photoediting capability through a reasonable graphics card
Have a reasonable hard drive for porn / music
Screen size not a huge issue as only at home, 15 enough though i think

Anyone seen any cracking deals out there, or ones particularly to avoid etc? Have had dells previously, but getting concerned with their build quality after the current one.
