We know some of the advantages of the tower configuration: The ability of adding and upgrading internal components, the freedom to choose your own display, the ease to add or change a DVD burner or other hard drives, or the plenty of internal expansion bays. But there's an argument for most people the smarter choice is an "all-in-one model", with the smaller decor-friendly footprint, portability, and recently, plenty of computing power.
Sony Vaio L Series VPC-L11S1E/S
This is a 24" HD display that comes with a touch-screen function. It has A 512 MB graphics card which makes it very capable for gaming. You can even achieve 31fps. Core 2 Duo and windows 7 pre-installed and 4GB of RAM paired with a 500 GB hard drive. 6 USB ports for all your peripherals. Too bad it doesn't sports the new line of intel processors.
Lenovo Ideacentre B500 0887-4AG
We love the ATI Radeon HD 5570 graphics card and its 1GB of memory, 35fps are achieved pretty easily. Quad Core 2.66 GHz with 4GB or RAM and 1TB of storage space. Bluetooth keyboard for less cables and 6 USB ports comes standard. This is a good value for the money.
This is a 23 incher that has a touch screen surface; and also comes with Invidia's 3D glasses. A 120Hz refresh rate and 1.5GB GeoForce GTX460 graphics card. 6GB of RAM and the more upgraded i7 Intel Core running at 1.73 GHZ. This is the best rig for gaming with steady 37fps. It can go 2D and 3D with no problems whatsoever.
