Here are some pictures of the dual beer engine keezer I built recently using ideas I got from this forum. I wanted a beer engine keezer that would look decent in my kitchen and be somewhat realistic. But I didn't want to pay $400.00 for a beer engine. I used Valterra Rocket hand pumps.
My local camping world keeps these in stock. I bought the Freezer at Home Depot it is the 5 cubic foot GE unit.
I also used the Johnson controls digital temperature controller.
My big stumbling block was that I wanted the handle to be inline with the gooseneck. With the Rocket hand pump in it's original form it is impossible to do. You can see the linkage system that I devised to accomplish this. I then bent stainless steel tube to make the gooseneck and I cut the spigot off the hand pump so I had a small stub sticking out the top. I then connected the gooseneck to this stub with plastic tubing that is routed around the handle and mechanism. I had some questions on the building of the goosenecks I bought this stainless steel tubing here
I used a cheap brakeline bender that you can buy at autozone or advanced auto or someplace like that. It is a plastic arch with a matching metal shoe on a screw assembly.
