It would totaly depend on what you mean by Belgian OSM site.

I would personally not use drupal for such a site but use a framework 
(staying in the PHP realm here) like Laravel4 or Symphony2.    But that 
also depends on what I have in mind for such a site.   I do think Drupal 
and wordpress is overkill, I use wordpress for my personal blog just 
because I'm a developper , so by definition I'm lazy and don't want to 
spend too much time. Drupal/Wordpress and the like are pretty much OK 
for a blog oriented site.

You could run this from a 20$ per month linode (see 
https://www.linode.com/ ).  In fact, using nginx as a webserver, mariaDB 
instead of mysqlDB and spending a good chunk of time tuning it, you can 
run several sites easily.  I have like 10 of them on it and also a piwik 
instance (~= opensource version of what google analytics does).  So 
another 10 sites use it to store visitor data in in (just like analytics 
do it).   I do have some caching going on , good practise anyway as most 
of the files are just staticly served but come from

If your goal is to start building up database, do tileserving or create 
nominatim DB's, the specs go up a lot.  Then you would arrive in the 
price for a cloud server range of a co-located server, cloud servers 
aren't suited either for heavy indexing,  a solution for that would be 
to use a something like a EBS device (elastic block store - see 
http://aws.amazon.com/ebs ) and is expensive.

On the other hand, if you want a true 'beast' of a server, I would 
recommend (of course) linux + the Revodrive 3 x2 (personally I would get 
2 of those and stripe them over the PCI bus) see 
http://tweakers.net/serie/1908/revodrive-x2/

That drive has insane specs compaired to regular SATA SSD's.  Check out 
http://wiki.openstreetmap.org/wiki/Osm2pgsql/benchmarks  there is one 
that has numbers from a revodrive from the past, and you'll see why I 
would use that one.   The performance is huge compaired to the price range.

I would also not pay too much attention to CPU's.  Most of them will be 
able to server thousands of sites in the webserver scenario. Given the 
huge datasets in the latter case, I would totally spend all my money on 
RAM, the more the better as it speeds up postgreSQL and indexing 
exponentially.

So, question back:  What are you planning to do with the site ?
