High-end Gaming PC

I am selling my old gaming pc due to a recent upgrade. I built it around 5 years ago and have done a few upgrades over the years. I have an invoice for every part if wanted by the customer. Still runs like a beast to this day and can reach up to 500+ fps in most games. If you have any other questions, feel free to ask below.
