Bought most parts of the system in 2011, replaced monitor last year, replaced headset last month (+ got the sound card for the amp), got the SSD yesterday (hence the re-install)
Need to replace the mouse and keyboard soon, cheaped out on them.
Next year I want to upgrade the CPU, GPU, add another 8GB of RAM and PSU, or I might replace motherboard as well and go with an Intel system. Not sure yet.
