I will be updating this thread with Magnet links and Metalinks so that non-torrent users also have the option for verified multi-source downloads.
S3TC Textures Low End "MASTER FILES"

Shareaza, Peerproject, Quazza (or similar) users can help more as their shared files show up across more networks.
