I’m near to buy a server to do the rendering.
i try to explane:
Actually i’ve 2 pc (Dell dual proc. xeon)
but i loose many time to do the final render (many time in A3 - 4000 x 3000, and many time for the animation.)
so the idea is to purchase a server, with rack, at the start i think about 4 processor, xeon, every rack will have 1GB of ram, and only one rack with an HD … about 160GB.
i’ll install on this machine 3ds. and vray.
on a second time i’ll add more rack with more processor, that depends on how much work i’ll have 
what do u think about it ?
this have a sense ?
i’m realy frustated 'cause i loose to much time for the rendering and i need a damned fast pc.
Have a nice Day,
