I took the liberty to download your picture to my hard drive and then upload it into your gallery here on AutogeekOnline so I could insert it into the thread, (hope you don't mind), here it is...
I'll stick to my opinion that it looks pretty intermediate to me as I've see a lot worse in my career...

Is your PC the first generation or is it the new generation PC 7424
