Excellent customer service and great prices...can't go wrong!!!
Upgraded old Dell (AMD single core, Vista, 1 gig ram ) to Win 7 Pro 64 bit. Ran well. Installed new 4 gig ram. Runs like a new (500 to 600 $ range) laptop!! And was a very good & fast shipping.
Highly recommend for iMac. Fast shipping. Easy install. Great price!!
