I wanted a PC that was small (I have a tiny office) but could pack enough punch for 4K video editing and some gaming. This was my first ever computer build and has evolved slowly over the last 3 months, slowly upgrading parts and cables to become this little thing. I am very happy with what it looks and runs like at the moment, aside from the rather shoddy DIY side panel, which is just a place holder. I am having a bit of acrylic cut by a professional!
The Raijintek case is fantastic, would definitely reccomend using an SFX power supply, the case is much more manageable with a power supply of this size and the aireflow is much improved. The Sapphire pulse fits with about an inch of clearance to the front IO. You can get a much bigger card in there than the manufacturer reccomends.... Cable management is a bit of a headache, but I hope with the custom cables that it looks passable!
Another win was the Corsair H60 (2018), it fits perfectly and does a great job with the two fans in a push/pull configuration. I am very fond of how the AIO looks in there. Airflow is very good and temperatures are low and very stable.
I have over-clocked the CPU to 3.9 at 1.37v, no matter how much I pushed the voltage I couldn't get it stable at 4. Nevertheless, the CPU has more than enough processing power for my needs.
