I have been out of the system building game for a while(last computer is 6 years old) and I am about due for an upgrade. I am trying to follow the posting guide, but let me know if you need any further information.
Approximate Purchase Date: This month
Budget Range: $1000
System Usage from Most to Least Important: Gaming, Media Center
Parts Not Required: Monitor, input devices, OS, external storage
Preferred Website(s) for Parts:newegg
Parts Preferences: Intel Processor/ Nvidia Graphic
SLI or Crossfire: Yes / No / Maybe
Monitor Resolution: 1920x1200
Additional Comments: Small is good, and I am trying to decide between shuttle and silverstone built.
Here are the parts I have already picked out. I am not sure though if the graphic card will fit the motherboard/case and if the PSU can actually supply enough power to the Graphic Card.
It's great to have a small build for gaming. But for a budget of $1000 you can get much better components , albeit they'll occupy a larger space.
For $1000, you can get i5 2500K, 64GB SSD, better motherboard, ablity to upgrade to dual GPUs in future, and also a breathing space for all the components.
I would stay away from Shuttle because they use a proprietary motherboard. I had one and loved it, but when the motherboard went they told me it would cost $520 to send me a new one. Cost of a whole new barebones kit? $500.
The graphics card should fit. It has a length of 9" and the reviews for the case say it can fit 9" without modifying the case. And according to the sticker on the PSU, it's 450W continuous with 36A on the 12V rail, and has one 8- and one 6-pin PCI-E power connectors. So no fooling around with molex adapters, and it's specced for enough power and (even better) a good distribution of power, indicative of a quality part. 28 reviews and no complaints about the power supply, even though quite a few users are gamers. It all looks good.
I think you've chosen a pretty good build. I was looking into building a SFF gaming PC for a friend a few weeks ago and I missed this case because I was looking at m-ATX cases, none of which for some reason have good ventilation on the side, which is a problem for all of the video cards I was looking at, since they all vented inside the case instead of out the back. The case you've chosen shouldn't have that problem, and should hold up to gaming very well.
It's not quite what I would put together -- i5-2500k, Z68/P67, 1600 MHz RAM -- but you've put together a very good build and everything looks compatible.
