The Trigkey is inexpensive at just under US$300, but it thankfully sidesteps the terribly slow Celeron or Atom solutions for an older but faster AMD Zen+ processor instead. Even light HTPC multi-tasking can benefit from the aging AMD processor.https://www.notebookcheck.net/Trigkey-S3-mini-PC-review-Core-i3-like-performance-for-the-price-of-a-Celeron-or-Atom.676932.0.html
Still too expensive. You can get a decent 11th Gen Intel Celeron mini PC on Aliexpress for as little as 140USD.
