Get a DGX spark.
Ships with aarch64 Ubuntu 24.04.
Tons of cores and RAM.
Very quiet and small
UEFI bootloader - I installed Ubuntu 25.10 and ESXi arm edition just by booting the ISO
usb-c power input (kinda cool)
Insane connectx 200GbE RoCE networking
10GbE Ethernet
Oh and an nvidia gpu with cuda and access to 128GB of unified memory
It would be perfect if it had some kind of BMC or IPMI/redfish and an exposed PCIE slot. But this thing is an awesome arm64 workstation no doubt.
May try to install to a USB drive and hang another gpu off the nvme port just to see what happens
