Why is there a 32bit variant of win8? Are there people who actually use win8 on non-64bit systems?
The last 32-bit NetBurst (Pentium 4) systems with 2GB of RAM aren't that bad to work on, when given a video card that supports Windows 7/8 video features and a decently fast disk.
You don't need a whole lot more to run a greenscreen terminal emulator or a basic web browser.
