Hard drive
When choosing one there is only to look after speed and capacity. For normal work you need at least 250GB of space and in terms of speed there are hard drives running with 7200rpm and some with higher performance at 10000rpm. Most use ATA or IDE connection with computer.
So what do you want to get?
If your computer will be used for:
Word Processing: 160+ GB, 7200rpm
Web Surfing: 160+ GB, 7200rpm
Light Gaming: 250+ GB. 7200 rpm
Heavy Gaming: 360+ GB, 7200 rpm
Digital Music: 500+ GB, 7200 rpm
Graphics Editing: 500+ GB, 7200 rpm
Digital Video: 750+ GB, 7200 rpm
If you look from this perspective: common mp3 song uses 5mb of space, common video from 700mb to 1,5GB. You know for what you will be using your computer so it is your choise.
ATA and IDE are quite similar, their only difference is that the ATA drive is more easy to install, and has less cables.
Memory
Also a very important component, it sends the message to the processor how to manage the orders which we have given to the computer.
There is never enough RAM. How much you need is relevant. If you play games which take a lot of ram or other memory consuming processes then you need a lot of it. Minimum amount is 1GB, middle 2GB and the best is from 4GB above.
The type is also important. DDR2 and now DDR3 are the most common today. Here are some RAM-s from slowest to fastest:
DDR2 400 MHz or PC2-3200
DDR2 533 MHz or PC2-4200
DDR2 667 MHz or PC2-5300/PC2-5400
DDR3 800 MHz or PC3-6400
DDR2 800 MHz or PC2-6400
DDR3 1066 MHz or PC3-8500
DDR3 1333 MHz or PC3-10600/PC3-10666
DDR3 1600 MHz or PC3-12800
The speed also very important. Why would we need a big capacity if it wont fill up enough fast. Memory can be upgraded very easily so do not bother buying too much or too expensive.
