Is the Apex Zen good for 1440p gaming?

Yes. The RX 9070 is the strength of this build and handles most modern games at 1440p on high settings. Expect high frame rates in shooters and smooth play in demanding single-player titles.

Will the Ryzen 5 5600 bottleneck the RX 9070?

Sometimes. In GPU-bound games the pairing is fine, but CPU-heavy titles and high-refresh play can be limited by the six-core chip. It is the weakest link in the build.

Can I upgrade the RAM later?

Yes, the 16GB DDR4 can be expanded, but you are limited to DDR4 on this platform. Moving to DDR5 would require a new motherboard and CPU.

Is 16GB of RAM enough for gaming?

For most current games, yes. Some newer titles and heavy multitasking benefit from 32GB, so plan an upgrade if you stream or keep many apps open.

Is this a good first gaming PC?

It is a reasonable starting point if you want strong graphics performance without building. Just know the CPU and memory platform are older, so future upgrades are limited.

What comes in the box?

You get the assembled desktop with the Ryzen 5 5600, RX 9070 and 16GB DDR4 installed. Check the listing for whether a keyboard, mouse or monitor is included.
