I built this PC almost 2 years ago but didn't get round to uploading until now (Feb 2019).
Originally I had made this for my girlfriend so she could do her work and play games. We then moved in together and because I made her a better PC than my own I decided to use this one as our computer for our new place.
I'm not too sure how much this all cost me as it was a long time ago, but I believe it was somewhere around £600 including Windows, the RGB lighting and the sleeved cables.
The reason this PC costs a fair bit for not much power is because I wanted it to look pretty and neat, although it's still pretty good for most games.
Please feel free to ask any questions :)
