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 :D (make sure its SATA)

those sticks will be fine as 2GB is the max
