Finally got a chance to sit down and write down what I picked up at the large trash pickup point in my neighborhood last month.

Two desktops plus two PS/2 keyboards: one clearly bundled with that white eMachines (plus a Hello Kitty magnet 😉 ) still in its original plastic bag with green Acer logos.
The black ATX case was kinda messy: rusted and dusty grills, but dual fans on both side and back, along with removable HDD at front and eSATA in the back, plus S/PDIF fiber optic, hinted this might be a high-end build.



And...... turned out the video card is a low-end Gigabyte GV-R455HM-512I (Radeon HD 4550), on a GA-965P-DQ6 (rev. 1.0), with Transcend DDR2-667 1GB ×2, two identical Seagate Barracuda 160GB 7200rpm (as expected, their content were >90% identical, possibly configured as RAID 1). Cable management was nonexistent.

I was expecting a Core 2 Extreme or at least Core 2 Quad CPU, but turned out a low-end Core 2 Due E6300, and the removable HDD was a broken and extremely small 6.4GB Seagate Medalist:


Heck, 2.5" PATA HDD with at least 20GB capacity in USB external casing was already quite common in 2006 (GA-965P-DQ6 was revised to 2.0 at the end of 2006); dunno why the original owner decided to install a rather outdated technology.
I didn't expect that eMachines build with any high-value component, yet with the exception of yellowed plastic front bezel it was kept quite nice and clean (and it had a genuine Win7 product key sticker!), so I powered it up directly.



The bundled Radeon HD 4350 had no image output, so I replaced it with that HD 4550 from the other machine...... and it went straight into Win10 desktop without even asking for a password! The poor HDD, a Seagate ST3500418AS 500GB 7200rpm, kept running at >95% workload and simply couldn't stop. I terminated processes and uninstalled programs one by one, finally pinpointed the problem: Adobe AIR. Now I can tell why the original owner threw it away without removing personal data: the HDD was slow enough (by installing Adobe stuff) but with very limited knowledge on computers she couldn't replace it with SSD, then one day the video card died.
The RAM was a single stick of 2GB DDR2-800, but this bloody MB had nForce 620i northbridge: single channel at 667MHz max. I just don't understand why Nvidia kept producing those NB chips in 2010 when DDR3-1066 had already become mainstream. 🙄
While the result was a bit disappointing, hey, they were all FREE, and at least I got a Pentium E5700 (right now the fastest 2C2T LGA775 CPU I've got), three strips of DDR2, three SATA HDD, a SATA and a PATA DVD+RW Super Multi, an old but functioning Seasonic 430W PSU, and bunch of SATA cables. 😅
