Hostaffect is right eBay is ok if it is just junk you want or that new semi stolen mobile phone but for a data centre you need equipment that if it goes wrong with in the first 12 months you can get a replacement or repaires.

I would Recomend looking on a search engine for your country and look for a decent dealer or for a company that ships to your country.

Anyway good Luck with your search
