How much d'you have to spend on the drive? If you can afford it go for a higher capacity drive like a 500giger, as the denser platers will give slightly better performance, you'll have much more space and i don't think they're that much more expensive?
Well, I have enough to get two 500GB drives... but right now on my current computer (Mac mini) I've only used 50GB of it's 80GB HD. And it's only a 5400RPM drive, which I'm satisfied with so far, so I don't need a super huge and fast hard drive.
My dad says I should go for the two 320GB seagates, but my head says go for two 250GB 32mb cache drive...
And on the memory, i don't see how the Corsair's silver heatspreaders really fit the colour scheme any better? If you're going for overclocks etc worry about the performance of the chips more than the colour of the heatsink.
Another person brought that to my mind also that the heat spreaders don't exactly match the color scheme very well... but if you haven't seen the post, I've decided to get the Crucial Ballistix Tracers (black sinks).
