The package you see in that link is standard - I've upgraded some but it only shows in my account, not on that link.
I've elected to go with NO mechanical drives, even storage. So will upgrade this package to the 250gb Samsung EVO or the 500gb Samsung EVO SSD for both internal drives. Probably the 500gb's ... and I'll add the dual 8gb RAM for a 16gb RAM package.
I buy 250gb SSD external drives for storage, and can add easily to those and link USB when needed -- and, it keeps less data on each drive just in case one happens to fail. I do dual backup on all RAW files, and then just pull a copy when I need to work it for a project and leave all original RAW files on a back-up external SSD ... I've lost data a couple times on mechanical HD, and avoid those like the plague once SSD became available.
Thanks for the info guys -- will probably read all the stuff I found on these and make a choice this weekend. The company is here, in USA - fifteen years, and seems pretty reputable - and has lots of 5 star reviews. When I call on the phone, I always get the same tech, no 'on-hold', and he's very savvy and mature. That's important, and it comes with a one year warranty and lifetime tech support.
And, regards the screen -- I travel a lot, so will use quality monitor when at home ... but for the road, this one looks pretty good.
