I was tasked with getting 20,000 PS5 APU's online. ASRock BC-250. Each chassis had 12 independent blades and in order to save money, we decided to not put SSD/NVMe into them and iPXE boot them instead. Each APU had 16GB of memory, but the only issue was that it wasn't ECC, so they would randomly fail.
It took a lot of effort but it actually worked!
