I believe the first image is the standard design of the Rostock printer. I did my research last month and I have finished building my Delta printer, now I am fine tuning my configurations.
My design uses:
Ramps 1.4
Arduino Mega 2560
Nema 17 steppers (6 pins but I only use 4 pins)
Reprap Discount Full Graphics Smart Controller (SD card slot not working on Marlin yet, but I love the screen)
Now I designed my layout a little different, but that's the best part about building, as long as you keep the basic angles.
I would suggest using Styrofoam to design your printer before making your first cut on your real material of choice.
