So after bouncing back and forth between a refurbished 15 and a new 13, I decided to go with the new 13 base. I went to the store and the 13 was the size I was looking for, and I really do not need a dedicated GPU or quad core power. Once I get it I will put in 8GB of RAM and I plan on putting in a M4 SSD down the road. http://www.newegg.com/Product/Product.aspx?Item=N82E16820148450 One concern is voiding the warranty, if I do the optibay thing would I void the warranty? Or if I just swap out the HD for SSD, leaving the disc drive alone would I void the warranty? Once I put the SSD in how do I transfer all my data to it? Another question, what is the best way to transfer the info from my old imac? Migration? Carbon Copy? Another thing, could anyone recommend a good reliable case that can still hold my power supply and some accessories that isn't to bulky? This is the best I found. http://www.bhphotovideo.com/bnh/controller/home?O=&sku=734822&Q=&is=REG&A=details And could anyone recommend a good Anti Glare screen protector? I heard of imoshi ivisor and power support. Thanks for and input, really excited to replace my late 2007 imac!!!
