If your looking to build a simple water chiller, then the best system to assemble would be to buy a condenser unit that is rated for the watts you will be cooling and a plate HX. You can find some good deals on Ebay to buy most of your parts. But, even going this route, you need to consider the tools and supplies you need to put the system together. This can be a very expensive hobby and it may be best to have someone build you a system for your needs.
I lost count of how much money I spent since I started building my system. I admit, I've went a little over the top, but its something I enjoy doing.:D
