Check this out
It has 8 GB and a 1 TB hard drive and is about a hundred bucks cheaper. I bought one just like it last March. It's been 100% reliable. The only problem I had with it was getting the speed from the USB 3 ports. I finally got a combination of drivers and hardware (a Sabrent hard drive enclosure) that works like it's supposed to, and have very cautiously avoided any suggestions to update any drivers! Since it's been 10 months I would hope Dell and Intel (who makes the motherboard with integrated USB) have gotten their act together, but all I know is that when I finally hit on a combination that works for me, I haven't dared to make any changes.
Good luck.
