The original NTI PIX and the PIX Classic had cases that were sourced from [[Original equipment manufacturer|OEM]] provider Appro. All flash cards and the early encryption acceleration cards, the PIX-PL and PIX-PL2, were sourced from Productivity Enhancement Products (PEP).<ref>{{cite web|url=http://www.jma.com/PIX_History/NTI_1994-1995_files/Manufacturing_Plan.jpg|title=Notes on PIX production}}{{Dead link|date=July 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Later models had cases from Cisco OEM manufacturers.

The PIX was constructed using [[Intel]]-based/Intel-compatible motherboards; the PIX 501 used an [[Am5x86]] processor, and all other standalone models used Intel [[80486]] through Pentium III processors.

The PIX [[Bootstrapping|boots]] off a proprietary [[Industry Standard Architecture|ISA]] [[flash memory]] [[daughtercard]] in the case of the NTI PIX, PIX Classic, 10000, 510, 520, and 535, and it boots off integrated flash memory in the case of the PIX 501, 506/506e, 515/515e, 525, and WS-SVC-FWM-1-K9. The latter is the part code for the PIX technology implemented in the Fire Wall Services Module, for the Catalyst 6500 and the 7600 Router.
