20GB Japanese PS3 (With PS2 Hardware Inside) YLOD +

Hi i have a 20GB Japanese PS3 which was working excellent until one day switched on and there was the YLOD. I did remove the cover and Bluray drive but didnt go any further, still have both. This PS3 was only used now and again (we have other PS3s) and is the original version which has the PS2 Hardware inside. Selling for spares and repairs
