OEM supplers in Europe?

Hi all.

I am in the process of building my first PC .. and have already got orders
from friends (on a non-frigging-profit basis, of course).
I have tried to source most of my components on the 'net, but realise that
if I am going to build several identical machines at the same time, it would
be far cheaper to approach a wholesaler. I have spoken to my boss, and I am
allowed to use the company name and details when necessary ... but I still
cannot find a supplier.
Can anyone please recommend a wholesaler in England or France? I may not be
the biggest customer in the world, but 6 processors, 6 hard disks and DVD
burners (with memory for all) amounts to (for me, anyway,) a small (large!)
fortune, and any savings would be really helpful.

I live in France, but a UK supplier (or German?) would work...
Thanks in advance for all replies.

Cheers.

Nick H.
