Nothing worth value comes for free in this world, and a seedbox is no different. Ask yourself this, if a seedbox provider is offering you a "free seedbox", then how are they paying for it? Seedboxes are hosted on a server that will cost money to run. As of 2012, I can't actually see any providers offering a complety free seedbox, although I see that biohost offers a free trial. 

I know where you are coming from. You want to download torrents faster, you want your home IP to be protected, or maybe you are trying to build up a ratio on a private torrent network, and you need a fast seedbox to seed you files 24/7 at blistering fast speeds. Well you want all of this, and you don't want to pay a cent?

I suspect you are going to be out of luck finding anyone who will give you a free seedbox. There are a few very good cheap seedbox providers that offer a good service for less than the rental cost of a couple of DVD's, check them out.

All cheap seedboxes are not equal. Cheap providers typically over sell their hardware, so you are sharing the same server with many other users. This can lead to slow download speeds, and a very slow and unresponsive torrent interface. Two providers which we have checked out which are cheap, but also very good are:

Biohost

Biohost have a free trial, and they also have a range of very cheap plans starting for as cheap as $5. This is a small amount to pay for this sort of service. Biohost have excellent customer service, and will help you with any concerns you have. Their servers are hosted in the Netherlands, so you should be safe from any of the laws that affect citizens in the US and UK.

100TBH

100TBH are a very good host, and their cheapest plan is $7.60 (€5.99). For this price you get 100 gig of harddrive space, which is very good, most cheap seedbox plans have only a very small amount of hard drive space.
