Designing an HTPC requires a compact motherboard.
Designing an HTPC requires a compact motherboard.
You're looking for a budget-friendly mini ITX motherboard with built-in video ports. A good option would be the ASUS ROG Strix B550M Mini or similar compact models from that brand, which offer solid performance for streaming and media tasks. Make sure to check compatibility with your PSU and RAM specs.
Similar options are limited to used units, and finding a more affordable board that meets these requirements should be difficult for the next year.
The more affordable the better. Check the used market; there could be suitable options available. Look at eBay and see if the UK profile is listed.
You're likely to end up paying more than twice the cost of the CPU for a compatible mITX board. For an HTPC, it's best to opt for a used one, like a 4770K with an mITX board. You'll usually find it at a very low price and it will offer much better value while still meeting your requirements.
