I cut aluminum with mine (and professional aluminum sellers cut theirs with their saw, but it likely costs thousands), but I will second the “be careful” part.
Aluminum can snag your saw blade (especially if you use a blade meant for wood, which I don’t recommend because it also produces messy output). Snagging can have dangerous results (saw jumping upward and losing teeth or more in the process).
Ensure the work piece is clamped down very well. Ensure that the saw is either on a large level surface or better yet - bolted or clamped down. Ensure that the saw jumping cannot hurt you in any way.
When cutting aluminum, push very gently. And when the raw material gets too small, don’t try cutting the last little piece. Small working material will increase the chance of accidents. I set my limit around 20 cm.
In case humanity forgets about how to make CPUs, some folks would still remember how to make stateful relays, magnetic core memory, punch cards and pneumatic logic valves.
It would take a bit of time from there back to a CPU.
