I'm about to pull the trigger on a new ThinkPad W520 and it seemed like this would be a good place to get some feedback on my configuration before I go ahead with it. Here's what I would have coming from the factory:
Screen: 15.6" FHD LED
Graphics: Quadro 1000M
Memory: 4GB (1 DIMM)
Storage Configuration: RAID0
Hard Drive: 2x 320GB
For the memory, I planned on getting 2x G.SKILL 8GB (2x 4GB). One thing I've noticed mentioned though is that there are configurations of the W520 that do not come with 4 DIMM slots? If so, I'm not sure if it would be more cost-effective to purchase it from the factory with 8GB via 4x 2GB DIMMs so that I can ensure that I'll have four DIMM slots, or if I should still just go with the 1 4GB from the factory and purchase 2x 8GB DIMMs.
As for the drives, I'll be taking out those right away and putting two 128GB Crucial M4s in on RAID0.
I plan on installing some sort of *nix or BSD right away, and from what I've researched there don't appear to be any unresolvable hardware issues with the popular distros out there.
So, just wanted to get feedback on this setup from the community here (especially about the memory). Thanks!
