Swwwweeeet! Genuine Xbox 120GB Hard Drive for 35.99!
To get it for 38.33 choose Royal Mail Recorded but you can choose other ways.
Ordered a router off these guys a few weeks back so very reliable and they are genuine Brand new drives but OEM without the transfer cable but you can a transfer cable from Amazon for about £10
EDIT: just noticed this was on HUKD a while ago but price is cheaper now!
EDIT: Apparently you don't need a transfer cable anymore and you can just use a compatible USB stick. Any one know what ones work?
