Recommended hardware for OPNsense in a home network with IPS/IDS, malware scan?

[Danielson3321]

I am planning to replace the default router from my ISP with a device running OPNsense to gain more advanced features, but I have doubts about which hardware to choose that best fits my needs.

Description of my network:

• Infrastructure:
  • I will use an external ONT that will handle the conversion from fiber optic to Ethernet.
  • A separate access point (AP) to manage the WiFi network.
  • OPNsense will be responsible only for:
    • Managing the traffic from wired devices and those connected to the AP.
    • Routing traffic to the ONT. (Is it possible that the ONT handles PPPoE and OPNsense would act as a router in double NAT?)
• Devices on the network:
  • Approximately 20 devices, including:
    • A home server.
    • A server accessible from the outside to host services.
    • Common devices such as PCs, consoles, smartphones, and equipment for streaming and web browsing.
• Required services:
  • Network segmentation using VLANs.
  • Intrusion detection and prevention system (IPS/IDS).[ /li]
    • Traffic analysis and malware protection.
  
  Key hardware requirements:
  
  
  • It must support 1 Gbps of traffic even with IPS/IDS enabled and traffic/malware analysis.
  • Low power consumption (it's a home network, and I'm looking for efficiency).
  • Quiet and compact (optional).
  
  Hardware doubts:
  
  I am considering several options, but I have doubts about which one would be the most suitable:
  
  
  • Mini PC from Aliexpress with Intel N100:
    • 8 GB of DDR5 RAM, 128 GB NVMe SSD.
    • Compact, efficient, and low power consumption.
    • Is it sufficient to handle 1 Gbps with IPS/IDS and malware analysis on my network?
  • Processors with QuickAssist Technology (QAT):
    • Such as Intel Atom (C3558/C3758) or more advanced processors.
    • Is the extra cost worth it for my home use case, or is it more geared toward enterprise environments?
  • Efficient portable hardware:
    • Based on modern low-power processors (i3/i5 or similar).
    • Could it be a viable option in terms of performance and energy efficiency?
  
  I would appreciate any advice, experience, or recommendations on efficient, functional hardware suitable for this type of network and my network setup.

I am still on my first appliance.   it's overkill for my 500Mb fiber connection.     
just get a device with a good solid state drive
