Hey there,

 

i'm new here, because yesterday the new hardware for my first ESXi Box ever arrived. I've bought the following components:

 

-Intel S1200BTL, C204

-Intel Xeon E3-1230

-4 x KINGSTON 4GB DDR3 1333MHz ECC CL9 DIMM w/ TS Server Elpida C (KVR1333D3E9S/4GEC)

 

So this afternoon i want to start with installing ESXi. But which version should I install for best compatibility: ESXI 4.1 or ESXi 5? When it's finished the Box should virtualize Windows SBS 2011 and Mac OSX Lion.

 

Thanks in advance and greetings from Switzerland.
