I am a newbie designing a computer for me and my family. For the last couple of weeks I've been choosing parts and watching clips of how to build computers. I've chosen some parts and am hoping someone could verify that they are all compatible and advise me on what power supply to choose. These are the parts I have already chosen:
I have a few questions first. Is there any specific reason you're going after a 3.5" 5400 RPM HDD over a 5.25" 7200 RPM HDD? If not, then I would suggest a WD Caviar Black HDD over what you have picked out.
I also recommend a SSD, and I would recommend a Crucial m4 64GB for that. If you boot windows off an SSD, it's the best way to boost performance for $80, hands down, and a far more efficient way to boost performance than investing in CPU, GPU, or RAM. IMO, SSD's are the best $80 you can invest in your PC.
Even if you decide not to go with an SSD, I would recommend this deal: http://www.ebay.co.uk/itm/Intel-Core-I5-3570K-3-4Ghz-Qu... over what you have picked. The upgraded Z77 MOBO is well worth the little extra money. Additionally, if you do go with an SSD, you will need SATA 6GB/s which Z77 offers. For the little extra money, you're also getting double the RAM capacity, HDMI output, and more USB 3.0's. Another thing to think about is the fact that the i5-3570k has Intel HD 4000 graphics, which would allow you to not buy a GPU right away and save money.
