cost

The whole thing costs about $1535-2190 USD

Memory Card

There are two memory cards we looked at - Kingston & Crucial. We have a max of 16 gb of memory over 4 slots. The max we could find was 2 gb / slot (for a max of 8 gb of memory).

Both Crucial & Kingston were well reviewed and both run about $200 - $250 for the 8 gb of ram.

wifi

We found out that all of the wifi have basically the same stats and price, so we decided that any one of them would be good.  Cost $15-30
