We tried to improve the situation with SiFive Unmatched: - 16GiB of RAM (twice more compared to SiFive Unleashed); - PCIe Gen 3; - M.2 NVMe (via PCIe switch); - M.2 for WiFi/BT card (via PCIe switch); - USB-As (via PCIe switch); - You can boot firmware (OpenSBI/DT/U-Boot) via microSD card instead of SPI-NOR Flash. With SD-Muxer you could update all those bits for testing; - mini-ITX (you can put those boards in the rackmount cases); - ATX power supply; - Front panel header connector; - Multiple fan headers; - and more. It's not perfect, but it's a decent upgrade for the 2nd generation SiFive board and the setup is way cheaper too. Pi KVM could provide some remote management (didn't try, might get one in the future to test).
