it lists Gembird in the long list of PSU brands to avoid.
If possible, could you please look at the PSUs that you have available for purchase that are in the range of 400 - 550w that are from the brands Antec, Corsair, Seasonic, or XFX and tell me if there are any?
If there are not any, can you please list out some other options besides the Gembird preferably in that same range?
I want to note here that the PSU and the Cooling system are two of the most underrated aspects of building a high quality computer. Both of them make a big difference in the performance and longevity of the computer and they are both worthy of spending a little bit of extra money on.
Case - A good case can go a long way toward keeping the inside of your case cool. This can prevent crashing and greatly increase the lifespan of things that generate a lot of heat like processors and video cards.
I don't know what cases are available where you are at either, but Antec 300 or Antec 300 Illusion are good cases, the HAF 912 is pretty good on a light budget I heard, the Storm Scout and Storm Enforcer are pretty good mid range cases, and Lian Li makes a wide variety of high end cases that are quite expensive but they can often be found on sale for a good price (like mine was).
Hopefully you can fit one of those cases into your budget. If you can't, let me know what cheap cases you have available and I will try to see which of them is best.
RAM - This is a big deal. The exact part number does matter. RAM is one of the biggest pains when building a new computer for the average person. Anything you can do to reduce the risk of problems is a good idea.
Have you checked the QVL of the RAM to see if the motherboard is on it? Have you checked the QVL of the motherboard to see if the RAM is on it?
Not just 2x 2GB from Kingston but the exact part numbers. It should probably look something like this KVR667D2K2.
If you don't want so much hassle to look things up but you want all the benefits of having compatible RAM, then go here
and hit "Show All Compatible RAM" and then select a part number out of there.
I generally suggest people with Windows 7 spring for 2 x 4GB RAM setups, usually 1333 and preferably 1.35w if possible. Usually a part number from such a thing is available from among those listed with those specs.
This part number CT2KIT51264BD1339 is an example of 2x 4GB RAM with those specs that is guaranteed to work in the board you selected.
