rack mountable ready cases for athlon uni and mp mobos?

[tekka99 at libero.it]

Hello all,
have you indications about manufacturers for cases optimized for racks:
1u or 2u ones? Also I think, if one plans to insert a pci slot on the
mb, he needs a sort of adaptator to be able to put the pci adapter
horizontally to preserve space. 
Any information on where to buy these items?
I'm particularly interested in rack thin cases for dual athlon mb (for
the moment only tyan, I suppose).
What about cooling ot these stuffs? How hot is the mp athlon system...
Anyone evaluated this aspect?
Thanks in advance

Bye,
Gianluca Cecchi
