Quiet fanless four-port house firewall instead of a loud used 1U: Protectli VP2420e
Quiet fanless four-port house firewall instead of a loud used 1U. Skip the retired dual-Xeon leftover if heat and noise matter.
VP2420e is the current SKU: Celeron J6412, 4× I226-V 2.5G, M.2 SATA (not NVMe), no eMMC. Official US support. Coreboot optional. Same silicon as the older VP2420 minus eMMC (Protectli KB, 17 Jul 2026). Official bare $359. Comparison grid flagged backorder on protectli.com/product-comparison/ when research ran. Older VP2420 official page $369, out of stock, bulk-only. Amazon configured VP2420 8 GB / 120 GB ASIN B0BQ1K182Y snap $539. That is the older SKU, not the e-model default.
Official max 24 W. Protectli KB wall numbers on the VP2420 (same J6412): Ubuntu idle ~8.2 W; OPNsense idle ~9.7 W; OPNsense + iPerf3 at 2.5G ~11.2 W. HomeNetworkGuy saw ~10 W idle / ~20–21 W under test on a smart plug. Fanless. Those are maker and published-review numbers.

Skip
Skip the used 1U pfSense / dual-Xeon leftover. The heater test is used vs new. Skip NVMe sticks: this slot is SATA. Skip treating Amazon Renewed as official Protectli. Brick vs 208 V 1U is the PSU rule. Shape is pizza box.
