Hey everybody,
I have a Dell Dimension E310 with an 80 gigabyte hard drive, and its running out of room. I'm thinking of adding a second hard drive. What I want to know is:
1) Is there another slot or whatever to add a second hard drive? I googled it and it looks like I can, but I'm not sure. It'd be great if I wouldn't have to open up my case to figure this out because the fewer times the case is open, the less of a chance I feel like "experimenting" and "checking stuff out" and "pressing ALL the buttons I can see".

2) Most of the hard drives I see on newegg/tiger direct/mwave say "oem". Usually oem means that it comes with just the main thing (in this case a hard drive) so will I need any extra wires or doodahs if I get an oem hard drive? If I do need some cables I have a slightly older dell, could I cannibalize that for the right parts? Also, what is the advantage/disadvantage of retail v.s. oem hard drives?

3) I assume installing a second hard drive is relatively simple, but just in case is there a good guide someone could direct me to? Is there anything else I should know? Is there a particular 500GB hard drive that is better than the others? (My budget is 75 dollars)

And then just in case it is important, I run ubuntu linux 99% of the time.

Thanks for your help,
PJ
