New Build

Hi, I'm building a new computer that has to fit in a very tight space and it needs to be powerful enough to handle windows 7 and games from at least 3-4 years ago (1-2 is better but I'm not going to be pushy). It also needs to be quiet as this computer may run 24/7 and is right next to where I sleep. I already have a case (http://www.newegg.com/Product/Product.aspx?Item=N82E16811112266) from a previous computer and need to replace pretty much everything else.

The following links are what I am considering, but are not a final decision until I get some pro's and con's (hopefully).
Motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813500060
Processor: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103849
RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231402

At the moment, I have a 10,000 rpm WDC1500HLFs hard drive that I can use but it's pretty loud and was thinking of getting this instead:

The one thing I am unsure of getting is the PSU because while I would not mind have a little juice if need be (I am planning on at least 2 hard drives inside), I would like to keep the power consumption down. Thanks for any help in advance.

 

My current psu is a 200w and is designed for a mini-itx case which means it's basically hanging by one screw at the end of the case. It's relatively new, I'd say less than 6 months but I don't think it can handle the new build. Normally I would agree about the RAM, but the mobo only has 2 240pin slots so I can't get a 4 stick set.

 

I'll certainly consider the ram but I thought that the whole thing was that you need lower CAS latency, the corsair has 9-9-9-24 and the one I found has 7-7-7-21 and voltage is about the same (1.6 for the corsair, 1.5 for the G Skill.

 

I personally would not use Zotac as they are a budget brand - stick to the likes of ASUS and GIGABYTE
with regards to the CPU just get the best that you can for your budget
With RAM the difference in the latency you would not notice anyway and its only better to get lower latency if you plan on overclocking as it gives you a bit more headroom

 

The thing is that while I admit to wanting a "brand" name, the best mobo's with all the specs I want (on newegg at least) all seem to be Zotac. I had a jetway mini-itx that I went through horrible audio problems with in that it would be very low or cut out completely for no reason among other problems. The RAM I am still considering. The main thing is the PSU, if I should decide to go with the components listed or even with the other ram, what PSU wattage should I get (the lower the better) with perhaps one more hard drive to be part of the system.

 

At the moment, I have a 250w psu - would it be wise to get a larger one? It should handle everything, right?
