X61 Parts Help

[kazmierczak]

Hello,

I'm ordering parts for a new X61 build, but I want to make sure that this is decent stuff. I'm a novice, so I have a few parts questions:

• I don't have a charger, and I'm worried that it might damage the computer if I get a low quality one. Should I just go with a used lenovo original, or do you guys have any advice on getting a 3rd party new one? *edit: I'll just try to get it from the lenovo website, and they sell some on Amazon that seem to be of decent quality if Lenovo doesn't sell any: https://www.amazon.com/Listed-Lenovo-Th ... merReviews
  *edit: was about to drop $55 on a charger from Lenovo's site. Thank god I found it on Newegg: https://www.newegg.com/Product/Product. ... 6834995032
  
  Is this a decent wifi card? (https://www.ebay.com/itm/Intel-Centrino ... 2749.l2649) Do they matter all that much besides lowering palmrest heat?
  
  What do you guys think of this RAM? https://www.ebay.com/itm/4GB-2x-2GB-Mem ... 2749.l2649
  
  Is there any way to check if these parts are actually new?

That photo looks like a knock-off of an intel 6205N card.
This one looks like an original:

Hey,

Do you think the quality will be lower?

And I assume there will be a way to check right?
