After 16 years of using notebooks as my primary machine, my 2019 PC has seen me return to the desktop. My Macbook Pro is great for colour accuracy, however Apple's lack of ports and inflexibility with upgrades has steered me away from Macs. After looking at some of the prebuilt machines in work (from Lenovo, HP, etc), it's easy to see how you have no idea what kind of components and build quality you are getting from the big manufacturers.
I've built many PC's before, and Windows 10 is in a much better state now than Windows 8 was. I figured why not.
I wanted a machine with plenty power and speed that could be future proof enough for the next 3-5 years. For my photo editing, I wanted lots of storage for RAW files, and the ability to add more drives in the future. I wanted to be able to do some PC gaming and have a graphics card that could help render videos. The monitor also needed to have some kind of colour accuracy.
PC cases have come a long way since the 2000s and the H500 was amazing to build in. Clean and simple with great cable management. My only complaint is the lack of a front panel USB-C port.
The build was extremely satisfying and came out better than I thought possible. The machine is fast and quiet considering I'm using the NZXT stock fans with it right next to me.
I don't think I can buy another pre-built machine again.
