This is an entire computer !! I do have an external 2TB hard drive and of course the wireless mouse and keyboard plus the big TV and it runs of a charger like a cell phone...but that's it !! Two USB ports,HDMI,RCA video output, mini stereo and SD card slot.700hz chipset,512 RAM ( plenty for Linux) onboard graphics and wired ethernet ( but WiFi usbs are only like $15 now).It is called a Raspberry Pi and costs around $40 including shipping!! Running a scaled down Linux and I am going to use it for a media player at the lake. The 2TB hard drive will hold about 2500 movies !!! The picture is a solid 1080p and clear as a bell.
Here is the keyboard..
I produces almost NO HEAT so it can be kept in a little cedar jewelry box. I did drill some holes in the bottom and a few in back for the cables just in case. Here is the Wikicrap if you care. I bought mine on Amazon and had it the NEXT DAY !!!
