For the PSU, you can calculate how much power you will need here: http://images10.newegg.com/BizIntell/tool/psucalc/index.html
For the graphics card, I've heard that the 7850 gives you better bang for your buck than the 7870.
The Hyper 212 is a good pick as long as you don't get RAM with heatsinks that stick up more than a couple inches...
You might look at Acer monitors and see if they're any cheaper than Asus monitors...
That doesn't factor into efficency and power loss throughout years. Add 200W onto what that gives you is what I call for.
Depending on what RAM you get there might be some clearance issues. I know my RAM and heatsink are having some issues with clearance because of how close the RAM is to the heatsink/processor.
Again, meh. Remember, the platters are puny and if he's going to access any total of files that's above 8GB and if/when the NAND, which basically acts as cache, doesn't flush, his performance will drop drastically. I would just get a good 3.5" HDD with a higher platter density. WD10EZEX is bare minimum or the 1TB/Platter WD Green counterpart. He can also go with a Seagate or Hitachi 1TB/Platter drive if he wants.
Mid ATX? That doesn't exist you idiot.
I thought it was something like candyfloss, buttcracks, and pandas.
The motherboard I'm a bit meh about. Vengeance RAM is fine, I guess. I just don't like the look of it. I would go for the low profile ones if you don't want any clearance issues if you're going with air cooling due to the fact that you aren't going for a standard ATX sized motherboard.
People need to stop calling these drives by the Caviar name. The Caviar name is dead. Now it's just WD Blue, WD Black, etc. instead of Caviar Blue, Caviar Black, etc.
There's a list of recommended SSDs on OCN. Like what Sean, the maker of the guide, says, just go for the least expensive one on the list at the time since they all perform relatively well.
The case...meh with me but if you like it and if it has decent airflow.
Seems fine. You can use PCPartPicker to determine the power consumption or look at things like benchmarks that show power consumption under load of i7 chips. PCPartPicker doesn't have server processors in its database so it doesn't account for the TDP of that.
Sapphire is a good company too, but just go with the MSi.
I usually look at IPS and VA monitors (and PLS) so I usually don't give much of a damn about TNs but I've heard good things about Asus monitors.
The keyboard...meh to me since I have a Filco mechanical keyboard but if you're fine with rubber domes, I guess.
Issues with acceleration due to the fact that it's using, I believe the Avago ADNS-9080 or some other laser sensor that's close to that. I would go for the G400 as it can go up to 3200dpi I believe. Optical these days is probably the best way to go IMO.
Crap, I was talking about cases.
The platters are puny but the reviews aren't too bad for them.
ATi is dead but you wouldn't call a graphics card the AMD 3870 would you? Caviar may be dead but the drive he is buying is still under the Caviar name as it is an older one.
