The panel PC consists of a PC-based computer that is housed in a plastic
rear panel and a metal shielding case. Your HDD, SDRAM, power sup-
ply, CPU, and so on are all readily accessible by removing the rear panel
and shielding case. Any maintenance or hardware upgrades can be easily
completed after removing the rear panel and shielding case.
If you are a systems integrator and need to know how to completely dis-
assemble the panel PC, you can find more useful information in Appen-
dix C.
