Yep. Same here. ;-)

Absolutely right. Depending a little bit on the DB and WebSite layout  
and on the actual requirements, but yes - it's not really a kick-ass  
machine ...

Depends. As I said - if the whole DB fits into the remaining space,  
and a lot of website backend DBs do, it might just work out. But this  
seems not to be the case - either the site is chewing on seq scans  
all the time which will cause I/O or it is bound by the lack of  
memory and swaps the whole time ... He has to find out.
