Okay...I have taken it apart properly and had a look. It's a prebuilt job as i suspected, and the board wont allow a better cpu, and i cant get a new board cos it wont fit in the case. Sooooooooooo...PLAN B
I'm going to the computer markets next week and buying a new case and hard drive, and i'll build one from scratch. MUAHHAAHAHAAAA.
Stay tuned, this workog will be updated with the new case next week!
