I just installed LXDE F12 spin on a old PIII laptop with 128 RAM ( which runs fine btw and
it's boot time is ca 10 seconds longer than on latest version of Windows (7 ) on much
more powerful HW ). I had to remove the laptops disk and install F12 LXDE via external usb
on another laptop due to Anaconda refusing to install without minimum of 256 MiB RAM.
Filed bug #571439 Got closed wont fix.
This Anaconda behavior will affect all spins ( such as LXDE ) that target users with low (
memory ) HW ( usually old hw ) not sure if there are any cpu restrictions as well..
Just a heads up..
