I want to start by saying that I don't need this system, having recently completed my Madame Rouge build so I'm giving this 'Old Dog' to a local organization that provides low-income families computers for their children.
My neighbor knows that I'm a "computer nerd" (his words) Systems Admin, so he came over and gave me his Dell OptiPlex 780 SFF which wasn't working, saying that it's mine if I can get it working again. Well, Challenge Accepted. :-P
Honestly, it wasn't that difficult to get it working again*(see comment below): it was just dirty inside the case, the thermal paste was nearly gone causing it to overheat, and the only stick of RAM (2GB) was bad. It had a low profile graphics card in it which looked to be in good shape, and at the time I didn't know which card it was. After a bit of research I discovered that it's a Low-Profile EVGA GeForce 210 (1GB).
So I cleaned it out really well- applied new thermal paste, upgraded from a Core 2 Duo E8400 to a Core 2 Quad Q9550 that I found for $45, I got 4 x 2GB sticks of matching RAM. a SATA power cable splitter to allow for two HDD's, one of which is a 120GB SSD that I had on hand; the other HDD is the Seagate 160GB drive that came with the system. I also included a Nano USB WiFi adapter which cost me $8 from Newegg, just because I felt like it. Works really well too.
I posted a benchmark picture comparing the GeForce 210 against the 750Ti and of course the results are rather dramatic. :-P
*I have to say that there were some complications that I had not foreseen, but it was a result of my tinkering with it; I thought that I'd be clever and use the low-profile Gigabyte 750Ti that I have on hand but discovered that it wouldn't fit properly unless I left it looking 'ghetto'. (Admittedly the 210 looks ghetto in the system as well, but not as much as the 750Ti does. :-P ) I don't have the time nor the resources to mod the case to make it fit so I changed it back to the GeForce 210 that came with the system. Little did I know that going from the 210 to the 750Ti then back to the 210 would cause Windows 10 to go haywire and not boot properly. I debated between doing a fresh install or going with the built-in Windows reset feature, but since I have never used the reset feature I went for it and it does indeed work. Takes a long time to reset, but it did work. I then re-installed the 210 drivers and all is well with 'Old Dog'.
Anyway, I feel pretty good about giving this system to an organization that helps out those in need. I'm probably going to make this a bi-monthly habit, but with different systems that I can find for cheap. :-)
For being an old CPU, it runs really well. I had no issues with it shutting down or running benchmarks. For $45, I think I did well.
8GB of RAM makes this old rig seem refreshed. A wise $30 investment.
It might not be the best SSD on the market, but it is an order of magnitude improvement over the included 160GB Mechanical HDD.
Not a bad OS. Does what it needs to do and should you screw up like I did it has the ability to reset itself.
Wireless Network Adapter
This little guy works great. Sure it won't have the range/speed of a PCI-E card, but if you want quick and painless WiFi you can't go wrong.
