says that the cost of building some mini-itx with enormous ram costs a lot (more than te mac studio), and with a lot of headaches with custom designing, cnc and stl. worth it?
also the power consumption will be higher than mac studio.
assemble the machine with proper thermo, wires and some open space, then enclose the thing with design.
the weight:
mac studio (m1 ultra) for 3.6kg
mini-itx machine: 6.3 kg - 10 kg (won’t lose weight)
graphic cards
a100 80g
a16 64g (with self-designed thermal solution)
