I have been lucky as I historically used foam sheets for old CPUs but the AM2 up use a small plastic clam shell that is convenient.
I noticed single CPU clams were cheap and I also found trays that can hold several processors.
Bent pins can be straightened with a mechanical pencil that has its graphite removed.
The old Sempon is now in clam safe. I trashed the old heat sinks as cheap new fans have have better thermal capacity. Neither HSF however failed as AMD uses ball bearing fans. I use the same type for my chassis fans as they last for years.
I might buy a CPU tray as it would complement the set of RAM trays I use for storing memory.
