The board had been used for a few years and then was returned to Scan.co.uk with the CPU and RAM modules to check for faults. The motherboard and CPU were fully tested and passed and the RAM modules were faulty and replaced. The board was sent back to me but unfortunately never used again as I was moving house and had a laptop that covered my needs. I have since unpacked and found the components hence the sale. Please be aware there is some small scratches on the back of the board near the audio ports. These were there when the board was tested by scan computers and passed, and I never experienced any issues with the sound. This is the reason for the lower price. If the audio does turn out to be faulty, a cheap sound card is all that is required (£10)
