The Counterstrike dudes have released their final version of the mod, and you can get a local copy of the upgrade version here
A full list of mirrors (excluding us) is to be found over at The official Counterstrike site
If you want to see what you're going to download, then you can go over to Gamers.com who have over 100 pics of it.
Btw : if you don't like to download it, CS 1.0 has gone gold and is on its way to the stores (let's just hope there are no bugs in it :p)

Update : almost forgot to say that both full version and the linux port are also locally available here
