What site can I get Free Items?

I was curious if there was such a site if you could actually get free items such as free electronics going into Computers, Game Consoles, Cameras, Cell Phones, Etc. You get the point right?

I was looking into getting a iMac but sadly I have no money to buy one because there to expensive "above a $1,000 dollars" or possibly and Mac to put it simple thats mainly all I want..

I was looking into new computers, that are very powerful for gamers, laptop or desktop thats why I chose to simply get a Mac because of the Specs but I also saw the Alienware Computers and there just as expensive, but the problem with getting them is of there prices so I was wanting to know if there was a site to get free things such as what I explained above,

But not a site that you have to go with money (Credit Cards) for offers, Offers I don't care for such as those with filling out a survey over a site and registering to complete the offer, but to keep it simple a site thats secure thats not a scam, of course, and free. Have any idea of any site that i could look at?

A lot of details and of course a link would do just okay, but thanks to anyone who could help!

Edit: To this I once saw a site dealing with registering and you get points for completing something and with a certain number of points you can choose something from there list, more like winning but not exactly, just getting something in exchange for points. To this I don't know the site its just something I heard about but I have no idea over it but for what I know above..
