I have a IBM eServer x366 and I really would like to play around with Snow Leopard Server or Leopard Server. Has anyone had any luck or experience running a Snow Leopard Server or Leopard server on this machine if not do you think it will work ?

Specs

• Processor (max) Intel Xeon Processor MP 3.66GHz
  
• Number of processors (std/max) 4
  
• Cache (max) 1MB L2 per processor (single-core) and 2x2MB L2 (dual-core)
  
• Memory1 (std/max) 2GB/64GB PC2-3200 DDR II SDRAM
  
• I/O slots (total/hot-swap) 6/6 (per chassis) Active PCI-X 2.0, all slots supporting up to 266MHz
  
• Disk bays (total/hot-swap) 6/6 2.5" Serial Attached SCSI (SAS)
  
  
• Network interface Integrated dual Gigabit Ethernet
  
• Power supply (std/max) 1300W 1/2 hot-swap

I also have a Google Appliance server

GOOGLE GB-1001

• Pentium III 1.26 GHz X 2
• 2GB RAM (4 x 512MB)

Has anyone tried running hackintosh on it ? If not do you think it will work ?

I think it might work with the Xeon because a Mac Pro with a Xeon CPU does exist......
You may want to try TonyMac's method with his Chameleon and iBoot Legacy.. probably your best bet.
