Ludicrous suggesting that they take it to a shop for such a minor issue as having filled the boot drive with media.
The other thing I would suggest is to not use Torrent software at all, but to use a seedbox to download them for you, offline.
Otherwise, you may have situations where you need to keep your PC on all of the time.
Your torrents will be stored in the Cloud, ready for you to stream or download at any time or place with an Internet connection, via Phone, Tablet, Laptop, Desktop, TV....
Using Torrent software and downloading/uploading directly from your device, is so last decade and is so limiting.
