RE: Upgrading Inspiron 7720 (17R Special Edition/Turbo Edition)
I have had this model for over 3Y now & upgraded one of the 750GB HDD to a 1GB Samsung SSD & the other to a 2TB Seagate HDD, so plenty of storage space. I use the master card as a document store now as the drives do not need to be any faster. I ordered a backlight keyboard from Dell & got a laptop cover sticker to improve the appearance. The RAM is 8GB & the CPU/GPU are fast enough. The battery has died, but I have not bothered to replace this as yet. Only issue with the machine is overheating so the fan needs to be cleaned every 6M which is a pain to get to. Great laptop if a bit big/heavy.
