I am looking to make a download site that will be similar to http://www.awesomestyles.com where users can come and download themes along with preview them and such. Which CMS would be able to accomplish this the easiest? I want to know before I put money into the project.
Most contemporary CMS does the job in almost all niches, you just to invest some money in custom developing the theme or templates. Many sites such as this one can be well powered by WordPress yet the visitors don't even realize it.
