IMHO, better use for 'integrated graphics' mini-system is a network-render box, a 'side-kick' for your existing system. Get as much RAM and CPU cores/threads as practicable. The queue-render is not displayed on networked system, so you can wind resolution & refresh down to VGA to make best use of CPU resource...

Okay, it is no substitute for a braw GPU card, but the work-flow is rapidly test-render locally using main PC's GPU, then send full job to 'box' as CPU-only. Now you can continue working at full speed on main PC...

The other side of coin is that GPU cards max-out as scene complexity rises. I found I must progressively 'dial back' vol-bounces and buckets from my twin cards' optimal 1024 settings. Eventually, the GPU cards just 'fall over' with any settings. But, there's no such limits on CPU-only renders, locally or remote, which just take longer.
