[Charlug] Can someone help me get a desktop?

[Pierre Abbat]

I need to upgrade littlecat. Currently it's a 300 MHz Pentium with 48 
MB, and it's running a mishmash of Mandrake 8.1 and Red Hat 5.2, or 
something like that. I got a 200 GB disk, but it sees only 135 GB. I'd 
like to run a recent Ubuntu, but it doesn't have enough RAM for the GUI. 
If possible, I'd like to have it in less than a week, since I need it to 
work on a program, but I can't pay for it until Dec. 8. If you know 
where I can get an inexpensive box, please let me know.
