I converted my Blender internal's model to Cycles renderin engine ,the blender internal version is also available on blendwswap ,the only thing i made is converting materials to cycles ,the model and texture are the same.the zip is crated with Ubuntu studio, the blender model that is also packed with the texture ,enjoy with it.
just turn up the sample for the render and you'd be golden, it'll remove more noise from the image the higher the amount of samples
