What are the minimum system requirements for Lubuntu? [duplicate]

I know the System Requirements for the Desktop version show that it is recommended on PCs with more than 1GB of RAM. but I have to mention 2 cases for me:

CPU: 700Mhz Intel Pentium 3
RAM: 256MB
HDD: 20GB
OS: Lubuntu 12.04
WORKS: Like a Charm 2.0 ^^

CPU: 550Mhz Intel Pentium 3
RAM: 128MB
HDD: 40GB
OS: Lubuntu 12.04
WORKS: Like a Charm 2.0 ^^

In both cases I am using Lubuntu and test it, well everything. There was no lag, no problems, no nothing. Just works and it truly makes the PC come to life. I mean they had Windows XP and the minute they had Lubuntu and the users learned in a day how to use it they told me they felt the PCs as if they were brand new. They even booted faster.

Another case is a laptop I have here:

BRAND: Dell Latitude CPx Notebook
CPU: 650Mhz Pentium 3
RAM: 128MB
HDD: 6GB
OS: Lubuntu 12.04
WORKS: Like a duck in the water. Like an elephant in Africa. Like my teeth on a Pizza.

And the last case which I mention also here: Lighter in CPU/Memory Usage: Lubuntu or Xubuntu is this PC:

CPU - Pentium 2 450Mhz
RAM - 64MB DIMM
HDD: 20GB
OS: Lubuntu 12.04
WORKS: When pigs fly!. I have to actually put 128MB RAM total to install it, then I took the memory and left it again with 64MB. I can't say it runs smooth but it sure beats the speed of others. Takes a bit longer to start (About a minute) and to open anything but come on, that is 64MB. My pen drive is 32GB. I can't ask the PC for more.

This pretty much gives you an idea. For your PC I am sure it will work correctly and smooth. I am even more sure that it will work even better than Windows XP or higher.
