Shipping and tax was $35.71, so the total cost for this build is 259.45.
Around January, I put together my first modern machine, and that's when I learned about the mini-ITX standard. I really liked the smallness of it all, so I wanted to create a PC that was as reasonably small as possible for someone like me to put together. I started out picking parts for any build, but all the cases and PSUs were sized for the ATX form factor, which I felt were just way too large. I learned that there were a class of PSUs that were much smaller than ATX, such as the TFX PSUs, so that's where I went. This also introduced me to new options for cases as well; I found two that I would have liked: the Winsis Wi-02 and the Inwin BP655.300. I would have liked to grab the Winsis since it was smaller than the Inwin, but some of the reviews on Newegg dissuaded me from it (e.g. cases not machined within tolerance, components not fitting in the case). Following the wisdom among PC builders, I did not trust the bundled PSU that had an obscure brand name (brand is "Power Man" for anyone curious).
The HDD and RAM came from my first machine, which was formerly equipped with 16 GB of RAM (bought before RAM prices started picking up) and 2.5 TB worth of HDDs (all originally cannibalized from other machines).
I have not installed the operating system just yet, but I plan on using Linux Mint Debian Edition.
