Hello, So after a few days of searching, I can't seem to figure out the answer to my question. The difference in price for a 512MB ram module for x86 vs. cube is about 2x ($33 vs $75). I've read some FAQs and the Apple knowledge base, and it seems like the memory marketed for x86 is electrically compatible. The Apple KB indicates that the memory must not have a height greater than 35 mm. Unfortunately, most cheap ram vendors don't display the dimensions of the dimms. My question: has anyone successfully installed cheap x86 ram in your cube? If so, from where did you purchase it, and how much? Thanks. /Alex
