    Good parts but you need patience

    The parts I ordered fit perfectly and fulfill my expectations but to get the parts the wait time was 3 weeks what is to long. For good quality parts that's the address but if you need things quickly there is probably other ones out there.

    replaced dead HD with ssd

    HD in 2011 imac died making it difficult to startup and awake from sleep. Already using an external ssd for great increase in speed. Swapped the dead drive for an OWC 256 gb SSD and now it can start up on internal drive or my external SSD. The internal SSD improves startup and the overall speed. I only expect to keep this unit a few more months and will then try to sell with the new Ssd. OWC instructions were great for replacement.. no problems replacing and installed with the temp sensor kit.

    I would recommend this product to a friend!
