Via are now manufacturing Motherboards to replace existing PC's with ATX Motherboards. Physically they are a direct replacement, but half the depth. These boards run the ARM chipset (Phone and Tablet chips) instead of Intel's chipset. They will not run Windows XP or 7 but will run Android 4.0 or Linux using a USB keyboard and mouse as well as using a touch screen monitor or TV. 'Windows 8 RT' would theoretically run on them but Microsoft will probably not sell their Operating System to allow this.
Foxconn, the iPhone manufacturers, are now making tiny fanless desktop computers which will sell for under US $200. They will come without memory, hard drive or operating system but will happily run XP or any modern Linux system such as Ubuntu or Fedora. Just add memory and flash drive of choice. These computers feature a dual core atom processor, USB 3.0, VGA output, HDMI output, wireless and ethernet.
