Spec me a HDD for a laptop and a desktop

[Jon20]

Hi guys, I'm looking to get a new HDD for my mum's laptop and my brother's desktop in preparation for Windows 7.

For the laptop I was thinking one of these: http://www.overclockers.co.uk/showproduct.php?prodid=HD-184-WD

For the desktop, one of these: http://www.overclockers.co.uk/showproduct.php?prodid=HD-081-SA

Anyone got any other suggestions?
