Question

Computers

Please advise a good mini-computer for the following requirements:

• PCI-E support (by any means)
  
• x86
  
• Cheap
  
• Little
  
• With little energy
  
• Can be bought in Russia (preferably common)
  
• Normal manufacturer (well, that's how it goes)
  

Full match to the list is optional. Thanks in advance!
