The Siemens 6ES7720-2AC20-0YB0 is a PG 720 C programming device — essentially a ruggedized field programmer for S7-300/400 PLCs, not a standard PC. It comes with 32 MB of RAM and an 810 MB hard drive, and has 5 slots for memory or interface cards. This is the tool you'd have on a commissioning cart to download blocks, force I/O, and run diagnostics on a live machine, not a panel-mount component.
