With an 18.4in high-definition screen, a 5.1 speaker configuration, a digital TV tuner and a Blu-ray player built-in, the Gemstone Blue is almost like a complete home theatre setup. It's fairly easy to use and it's a good performer, so it's a good choice for anyone after a desktop replacement.

A desktop replacement notebook with good speed and some versatile connectivity features that's also comfortable to use.

Once you get over the fact that you could buy several PCs at this price, the Alienware Area-51 m15x-R1 is an extremely capable desktop replacement for the keen gamer.

High frame rates and fast performance are hallmarks of this high-definition notebook, but it also looks fantastic. If you don't already have the funds for it, you might want to start saving like you've never saved before!

The Alienware m9750 is without a doubt one of the most powerful and feature packed notebooks we've laid our hands on, but it comes at a hefty price. Unless you're bent on portability you'd be much better off buying a desktop system for half the price and with considerably more power. That said, if you've got your mind set on a notebook, you need the power and have the cash, then you'll enjoy the broad functionality and classic Alienware style of this machine.

There's a lot to this notebook, and while it works great for the most part, it could still use a little refinement, especially with regards to its video input ports. Overall though, it's a great media centre notebook and it does have tremendous storage capacity.

It's hard to agree with this format as there is little benefit for a lot of work and considerably more noise. It's not that it hasn't been well engineered or that it doesn't produce good results, it's just that it doesn't seem worth it. For the same price you can get an equal performer with less of a heating issue and less bulk. As a desktop replacement it's fine, but as a notebook we're not impressed.

If you want some power under the hood but still need mobility this XPS from Dell is a great option. We're keen on the design and build as well as the features in tow.

Lenovo thrills us with many useful features on this IdeaPad Y710-200, but it fumbles the ball a little in its implementation of the 'Game Zone'. It's also let down by a lack of Gigabit networking and a digital TV tuner.

Until now MSI's notebook range had not really impressed us, but the GX600 is a fairly good performer with the added potential of the turbo mode. The inclusion of e-SATA and HDMI ports show that MSI has its finger on the pulse, which will help keep this notebook functional into the future.

A powerful desktop replacement notebook, which doubles as a media centre with a Blu-ray player. It needs some refinement, but as it stands, it's a functional unit for productivity applications and entertainment endeavours.

It's not an entirely practical solution for all types, as for this price you can get a very powerful desktop PC. However, if you're after a system with power and require portability, if not light and easy mobility, then this system has some merit.
