Cosmetic Condition

Interior Cosmetic Condition

The inside of this computer is actually very clean and looks good compared to the exterior. The motherboard is in pristine condition because it was new at the time of these photos being taken.

Following are interior shots of the computer, including it's internal components and expansion devices.

Here's another thing that's extinct on modern computers: Compact Disc Digital Audio. Back in the 1990s and 2000s, the system's data bus(es) were carrying an everincreasing amount of data. High-quality, low-latency audio being routed over the system's data bus only worked well on the fastest of computers. As an alternative, optical drives had a connector on them to route audio over a different, much less congested bus, directly to the audio controller. Additionally, the optical drive would remain at a slow speed as it was only decoding the data from the CD and converting it to PCM (Pulse-Code Modulation) audio instead of extracting it.

As systems got faster and data buses grew in speed and bandwidth to accommodate more data, the optical drive was taken into consideration. As a result, the data bus grew to handle the bandwidth requirements of extracted audio flowing from the optical drive in realtime, eliminating the need for the CDDA ports and cables. They then faded into computing history.

HI-POT OK means that the PSU has passed high-potential electrical testing. Unsure about ATE OK.

This suggests that this PSU has EMI and RFI filtering installed, which reduces electrical interference from switching devices and other components in it.
