Technically, computers.eu.com isn't a real domain, but a sub-domain of eu.com. Most domainers feel that such sub-domains are not worth anything, since they can be created for free from other existing domains.
If you think subdomains are worth anything then yes. (Not real domains but subs of eu.com us.com etc... ) Heres an idea, why don't you register any domain and create computers.yourdomian.com for $6.95 instead? Worthless IMO. I can guarantee you that the majority of those centralnic subdomains will be worthless to the seasoned professional. If anybody/company happens to shell out any big bucks for a subdomain, they obviously do not know the industry and are making a very UNWISE business decision. Centralnic is not required to follow an ICANN (ICANN.ORG) policy. However very smart business plan on Centralnic's side. They are generating income from almost nothing. I advise anybody to really think about and big public sale of a subdomain, I would bet that if there ever was one or one in the future that it could possible be a PR stunt as we seen in the past with even real extensions. Good Luck and be wise in your decision. Oh yea did I mention that theres many free subdomain services such as cjb, v3 etc...
