Lenovo IdeaCentre C300 All-In-One Desktop PC($450) is the cheapest system I’ve met so far. I’m doubt if there is a cheaper system as this new AIO PC from Lenovo. The previous AIO PC (Lenovo IdeaCentre A600) from Lenovo themselves even cost about $1000. And the lowest price so far is $530 for Gateway ZX2300 All-in-One PC.
In this Lenovo C300 All-in-One Desktop PC, you will find an Atom-based processor, has 2GB (max) of RAM, Max 640GB HDD, 1.3MP Webcam, 20-inch widescreen, WiFi (optional) and comes with XP or Vista.
The exterior design is pretty cool and artistic, somehow I think $450 worth the money even it’s for web browsing, doing light tasks, chatting and so on.
