Apple Mac Pro Early 2008 [As-is (Junk/For Parts)]

◎ Apple Mac Pro Early 2008 / ATI Radeon HD 5870 / 3 HDDs, Genuine Keyboard Included / OS Initialized [As-Is (Junk Item)]

○Product Description
This is a Mac Pro (Early 2008) being sold due to equipment consolidation.
While I have performed basic cleaning, including removing dust with compressed air, there are scuffs and signs of use consistent with its age.
I used this with an EIZO ColorEdge CG241W (also listed separately), but I am selling it as part of equipment consolidation.

Regarding Operation:
Due to age-related issues (see below), this item is being sold [as-is (junk item)].
Recommended for those who can use it for parts or perform their own maintenance.

■[Important] Issues and Special Notes (Please Read Carefully)
1. Memory Recognition Issue
Although multiple memory modules (totaling 18GB) are physically installed in the slots, the system only recognizes 2GB (1GB x 2). The warning light on the internal riser card is lit red, suggesting contact issues, compatibility problems, or age-related degradation, which are common with older models.
2. Booting Caution
Due to age-related degradation of components like the power supply unit, pressing the power button may only produce a click sound without booting up on the first try. In such cases, unplug the power cord, press and hold the power button for about 15 seconds (to fully discharge), and then try powering on again.
3. DVD Drive (Responds to operation, but the tray does not open)

■System Configuration
・OS: OS X 10.11.6 El Capitan
(Clean installed. Upon powering on, it will start from the Welcome initial setup screen, allowing you to configure it from scratch.)
・ATI Radeon HD 5870 for Mac Pro [Radeon5870 1GB]
・DVD Drive (Responds to operation, but the tray does not open)
・Storage (All initialized):
 - Bay 1: Empty (Includes tray and screws for SSD installation)
 - Bay 2: HDD 500GB (Hitachi)
 - Bay 3: HDD 500GB (Seagate)
 - Bay 4: HDD 1TB (Seagate)
・Accessories: Genuine Apple Keyboard, Power Cable

Thank you.
