The 'Build Your Own' Alternative?
Everyone’s idea of the “perfect system” is a little different, and that’s what drives enthusiasts towards the “build your own” market. But what if you can’t build your own? Power users have, for many years, begged for a standardized notebook form factor that would make “build your own” and “fully upgradeable” possible, but notebooks are far more sensitive to changes in technology than their desktop siblings. That is to say, if anyone ever did come up with a completely universal notebook form factor, a change in technology would make it obsolete before the owner ever got around to attempting a full upgrade.
However, many notebook components are standard or fall into a narrow range of interfaces governed by a standard. Most notebook drives, for example, employ a 2.5" form factor with a 9.5 mm z-height and SATA interface, making interchangeability between different models easy. The same is true of DDR3 SODIMM memory modules (and was previously true for DDR2 SODIMMs and 2.5” Ultra ATA drives).
Of these standards, the most interesting may be Nvidia’s MXM interface. What makes Nvidia's Mobile PCI Express Module (MXM) so interesting from the custom-build standpoint is that, even though it’s an Nvidia creation, many system manufacturers have used the format for their AMD-based graphics cards, too.
Of course, there is a little snag in the form of custom cooling, which still makes securing exactly the right parts for your own custom build a challenge. That’s why professional builders like AVADirect have become an important part of approximating your notebook dreams. The company sent us two custom-configured Clevo W860CU-based notebooks, identical in every aspect except for the graphics module and driver. Here’s the features table for the Mobility Radeon-based system:

Standing in for Nvidia’s top part is its GeForce GTX 285M, a component that adds $56 to the cost of the above system. Engineers and other 3D-rendering professionals will be pleased to know that AVADirect also sells an upgrade for the Quadro FX 2800M, though its $705.50 price increase will frighten non-professionals.
But, if it's like the P55, which it seems to be, there's the added uncertainty of the architecture thrown in.
Particularly with PCI-E being implemented differently, you might be seeing the inferior implementation of the P55 architecture responsible for a small amount of the relatively poor mobile performance. Since this implementation needs to multiplex the memory bus of the processor, you can run into situations where there is contention.
I doubt it's significant, but I'm curious why you wouldn't want to make a comparison with a more similar desktop platform. Was it because you couldn't get an unlocked Lynnfield to get the clock speeds for the processors the same in Turbo mode?
Granted, with a 45W CPU and 50W GPU, 30 mins is expected on a 40W battery if fully stressed.
So, is there any reason to own such notebuook?
The GTX 285M was a $50 premium over the 5870, and I am glad I chose to stick to the 5870. It is kind of strange one would pay more to have less performance. I guess thats what fanboyism are all about?
I have seen this model at other sites as well.
I think an ASUS JH73-A1 verse this would have been more interesting as its a bit cheaper for better parts.
