Intel PC requirement

I want to buy intel PC and install latest Mikrotik RouterOS.
What does work and doesn’t work with Mikrotik? Does Dual core prossessor work with Mikrotik RouterOS?

What are thing I need to look for when I choose the PC( Power, Processor, harddisk (IDE or Sata)..etc

Most standard PCs will work. Multi core, IDE, SATA are all supported. Avoid RAID, and only a few SCSI drives are supported in RouterOS v5beta6. Any new intel PC box should be fine.
