Honestly dude, use this:
Where's the closest Windows PC store? There isn't one. If your "custom" built laptop, that your brother made, stops working when you most need it, you are SOL.
However, Apple has warranties- 1 year factors, up to 3 years with Applecare. If something doesn't work, they will either fix it or replace it in under a week, and almost always for free. If the GPU on the custom laptop dies, you might as well throw it out...
