I had eComputer.info on my godaddy shopping cart and You took this seconds before me, I think it's worth max mid $xx when you will try to sell it to domainer and Low to mid $xxx if you try to sell it to enduser.
IMHO you wouldn't be able to find an end-user for these.
But you can easily find a domainer/investor for eComputer.info willing to pay mid-high $xx, if developed this domain could worth a lot.
