HP DL585 Server with Wndows 7

Goodmornig to all.

We're considering to buy different units of HP DL585 Server to build a Render Farm in order to render our 3D Images and Animations faster than ever.

Surfing the web we saw that the best price/power is this kind of solution: HP DL585 Server, with 4 QuadCore (16 cores), equipped with 32GB of RAM.

The only problem we're trying to solve is that 3D software (3DS MAX & VRAY) we usually use are compatible only with Windows 7 or, at least, Windows XP 64bit.

Does anyone know if this to type of OS can be installed on an HP DL585 Server?

Surfing the web we found out this video on you tube:
