Looks almost like it's never been used. You can definitely repair and replace a lot of the parts. Like Tin said, when you get it plugged in the first time make sure all the endstops and fans are working. The two fans blowing on the extruders, the two fans behind the extruder motors, and the fan on the X motor should all be running when plugged in. The bottom fan on the front is the print fan and is controlled with your gcode/host.
There is a carriage on thingiverse, but that's about it for 3d printed parts. I asked the person who posted the Workbench Apprentice Y carriages if they could edit that file to match the 10mm rods on the X axis, but haven't heard anything yet. They posted the .sldprt file so really, it just needs edited to match the correct rod diameter. I'm currently trying to so this in F360, so I might have one available on thingiverse soon.
