A few years ago, my Father in law got a new computer and I inherited an Optiplex 745. Because it was painfully sluggish and had XP as the main OS, this computer had been sitting around for a couple years without much use. I love how small and quiet it is though, so I decided to do a cheap upgrade with used parts. There are so many used parts available on ebay these days, that if you like to tinker with old equipment you can probably find anything you need.
After installing Linux Mint 19.3 on a SSD, I flashed the bios with the help of Rufus*. I Then upgraded the RAM from 2.5 GB to 6 GB using 2 sticks found on ebay. I also found a deal and upgraded the CPU from a 1.8 ghz Core 2 Duo to a 2.4 ghz Q6600 quad core, and then purchased a cheap low-pro video card.
There are still quite a few of these old Optiplex 745’s out there, and instead of tossing yours you might think about upgrading. I don’t do anything very demanding with this one, but for surfing, document creation/editing, light gaming and such, it’s a smooth performer. It’s a really decent backup box in case your main box is out of commission for some reason.
