The first time you turn on the laptop, you'll find it takes a little longer due to it completing the Windows System Setup - at least that's my finding on the box-shifter purchased or 'branded' systems I've purchased. Once it's recognised the hardware onboard they've accepted your U/P settings as well as your choice of profile data, it will load quicker nexttime.
I tried to purchase from Overclockers who seemed to have purchased the entire 1st batch of these laptops IIRC. At least that was how they chose to advertise their 'special price'. As a consequence, everyone who purchased this system from OCUK - got the ones with the dodgy harddrives and other faults. Those of us who were fortunate to have gone elsewhere received the updated harddrive and the system with the 'tweaks' already made. That said, the only 'problem' if you choose to call it that is that a RAM Checker program misreports the available RAM on-board for some reason, though that's not a problem. I've checked the RAM is there, its installed and working fine just the downloaded program misreports it.
Also system builders choose to have you the user 'burn' a copy of the OS due to costs, it saves them the $5 that they would be charged, plus shipping for including the media plus OS in the box or waiting for MS to ship them the disks. They can just download the OS, deploy then ship their stock, less waiting involved. Also, its worth checking out your system as on this one they included the User Manual on the desktop plus some other stuff. The 'Extra Crap' was a Added AV install that took all of a 10 seconds to uninstall, then I 'hit' it with CrapCleaner and it was clean, boot up takes around 12 seconds or so now. If it had been anymore 'infected' with crap, you could use the aptly named:

At the very least you'll be certain that what's installed IN the system is what you want in there. There'll be no virii buried deep in your registry of course, as you'll have blitzed it with everything else. Yet I've only seen I think 4 infestations of that ever and 2 of those even the stores that deployed them didn't know they were infact infected.
Anyway, HTH
