Hothardware published the details of the upcoming Asus Eee Box Desktop B202.

Quote: "Asus has released details at Computex today, regarding their upcoming Eee Box mini-desktop follow-on to the Eee PC. The Eee Box is based on a low-power Intel Atom processor and configurations with 512MB, 1GB, or 2GB of RAM will be available. Although the actual dimensions are posted, it’s the image from ASUS' booth that really gives a sense of scale. In the image, the Eee Box is standing next to a paperback book. These systems will feature Linux and Windows operating system installations that are very similar to the Eee PC mini-notebooks.
Pricing is said to be in-line with the Eee PC cost model as well. A 2GB model with a 160GB hard drive, for example, will cost only $299."
