Black MacBook "Yonah" HDD Question

[Trouble In 421]

I was wondering if there is an HDD limit on my MacBook, this is the hard drive I'm interested in.

Also I was looking to get a RAM upgrade and I would like to know any opinions or recommendations. This is what I had in mind considering my 32 bit architecture I know I'm limited to 2GB.

These are my specs:

Intel Core Duo 2GHz MacBook(MA472LL/A) : Black
L2 Cache : 2MB
System bus : 667MHz
Memory : 512MB of 667MHz DDR2 SDRAM (PC2-5300) on two SO-DIMMs, supports up to 2GB
HDD : 80GB 5400-rpm Serial ATA

There hasn't been a limit in 7 years to drive space addressing. I have a 320 GB drive in my MacBook.

No, you're not limited on the hard drive for your MacBook. And those RAM sticks look like they'll work fine

your currently limited to 1TB hard drive space (make sure its SATA)

those sticks will be fine as 2GB is the max
