The last of the PCs I found in the street that I could revive, canibalizing parts from the two I couldn't salvage.
That Optiplex 380 required more cleaning and fixing than the two 780 I already revived.
I had to adapt a PSU from a dead 780, adapting and soldering the power supply connector. i will eventually have to replace the PSU fan that is making an annoying noise. I have the fan, but since i need a few other parts that i don't have to finish this mod, it can wait.
I also had to cut the front panel that was to damaged. I put in a black metal mesh. Looking pretty cool actually. Removing all that plastic made impossible to use the original deported power on switch. Soldered a spare that I attached in the front panel, beneath the DVD slot.
The mainboard got a fluorescent paint job and everything else got a black mate paint. I forgot AGAIN to paint the DVD reader... looks ugly in the side window. Will do that when i have all the parts I need.
With a custom bios, the mainboard can take an adapted LGA 711 Xeon CPU. If I find one dirt cheap, I'll put it in.
I'll add 2x4GB of ram, a 240SSD, an HDD for as data disk, and some low profile inexpensive used graphic card. But for now it boots to linux and is quite smooth with only a spare 2.5" HDD, 2GB of ram, and the internal GPU.
Overall I'm happy with that build, once the few remaining details are fixed it will make a cool little win 10 pro PC.
Well, I decided to make this one a linux Mint PC. The color are matching perfectly, and it's looking just right.
I replaced the annoying fan.
I will keep for now the 250 spinning 720RPM 2.5" HDD, it's good enough for a web browsing, basic office tasks, video watching and music listening Linux PC.
The same applies to the integrated weak intel GPU. I'm supposed to get a super cheap Quadro k620, so maybe I'll put it in this mod.
After a bios update, I managed to put in 2 sticks of 4GB Corsair Ballistix DDR3. Interesting fact: the Optiplex 780 definitely doesn't boot with those sticks.
I also overclocked the Intel Core 2 E7500 with a simple BSEL mod with tape. It's not overheating, no need to adjust anything. It's now running steady and stable at 3.6Ghz.
I can still decide to make it a small inexpensive gaming PC: the K620 is not far from the performances of a GT1030, I would just need to install windows 10 on an SSD, and maybe buy some quad core xeon x5450.
But for now, I'm pretty happy with my little Linux Mint optiplex 380 that I found in the street...
