best linux for very low power server

whats the best linux for a very low power server
ram: 128
processor speed: N/A but under 1GHz
HDD: 160gb
Primary use: storage

Notes: needs a gui and to be lamp ready
Thx in advance

I've got Ubuntu 7.04 running on
128MB - 600MhZ Coppermine - 4Gig HDD

Installed via the "Alternate CD".

I've got a browser tab open to phpMyAdmin & another to phpBB3 running from that box as I type this message.

server or regular edition

CentOS

Most distributions will run fine on low specs.. just choose the "minimal" installation and don't install a X environment.

**EDIT**
You said should have a GUI.. don't need to use Gnome/KDE but something like Fluxbox.

i already installed debian with the the gui... how do i uninstall debians standard gui it and install fluxbox

be very detailed im new to linux

Trying to completely remove the GDM will probably break lots and lots of things and cause configuration headaches later. It will be quicker to start again and set it up properly from step 1.

I don't use any GUI whatsoever on my webserver (p2 266 with 256 ram) as there is really no need, and it lives in a rather inaccessible place. If you insist on installing a ram-hogging gui then it's as simple as "apt-get install <whatever>" and when you want to use it running it from the command line.
