First you should post in the macbook forum.
Second, your model number is mb466 (assuming you have the alu macbook)
I have heard that the alu macbook will support 8gb, however make sure you are doing activities on your computer that warrant that big of an upgrade in ram, as most people don't. Any ddr3 1066 ram will work. Crucial, gskill, etc.
The most compatible ssd's are either Intel or owc. I would stay away from ocz. Hope this helps a little.
is there something cheaper? i checked it out, it's too expensive :O
cheap, but good performance? what brand, and type
maybe the one that apple uses, i'd seen some problems with SSD's and i see the X-25 rumored to run w/o prob, but just to be safe :/ hmm i have a lot to consider lol
