Upgrade paths

RAM

16 MB of 80 ns memory via IBM MCA memory expansion cards · MCA was a closed, licensed bus, so third-party memory options were more limited and pricier than ISA equivalents of the era.

MODERATE

storage

Up to 115 MB internal hard drive via MCA-based ESDI controllers IBM offered on later revisions · The tower case had ample bays, but drives and controllers had to be MCA-compatible.

MODERATE

CPU

Locked to the socketed 80386 (16, 20, or 25 MHz depending on revision) · No official upgrade path between 386 clock speeds without swapping the whole system board revision.
