Here is the URL for mine, which is connected to my famous 670 ft sky loop antenna:

The "kit" from MassDrop is a not something you build, kit means it is the KiwiSDR board plus the BeagleBone CPU board. It comes with all the software installed, you just need to connect your antenna and provide a 5V DC power supply. I used one from a USB hub, a linear supply is best, I will likely change mine out for one, but I am pleasantly surprised that this switching supply does not cause any obvious RFI.
The antenna jack is SMA, so you will want an SMA to UHF/F/BNC/whatever adapter to connect your HF antenna.
You probably want to buy a metal enclosure for it, a cardboard enclosure comes with it (I guess to save money):

The KiwiSDR works as a web server. You need to connect it to your router via an ethernet cable. This means you do not need to install any special software or drivers on your computer, you use a web browser. And it works well with a tablet also. If you want to make it public, you will need to open up a port on your router and configure settings, there is documentation on their site for doing this.
