Our pick

The original Marantz CINEMA 70s is the starting pick when a 4.3-inch-tall chassis must also support 5.1.2 and 4K120. Choose NR1510 for a fixed five-speaker 4K60 system that benefits from its front HDMI input. Neither can be installed without the specified ventilation space.
Compare slim receivers for a low cabinet, with measured chassis heights, cable clearance and the speaker layouts each model supports.

What matters in practice
Select the speaker and video capability first, then verify a complete ventilated installation envelope. A chassis fitting through the opening is not enough.
CINEMA 70s is 4.3 inches tall with antennas horizontal. NR1510 is 105mm tall, roughly 4.1 inches. The other researched receivers are materially taller, so this article does not pad the shortlist with full-height alternatives. If the cabinet cannot meet the manufacturer's clearance instructions, moving the receiver is the safer installation decision.
CINEMA 70s is 15.1 inches deep, while NR1510 is roughly 14.9 inches. Add speaker plugs, HDMI cable bends and access space behind either. A cabinet door or solid rear panel can change both cable fit and airflow. The horizontal antenna measurement also assumes that orientation is suitable for the installation.
NR1510 is a five-channel 4K60 receiver with front-channel pre-outs. CINEMA 70s adds the two channels for 5.1.2, three fast HDMI inputs and seven full-range pre-outs. Neither offers four physical heights. Verify that the Amazon offer is the original CINEMA 70s described here because Series 2 is a separate model with its own specifications.
