Thanks for the answer. I asked a friend for advice, and that's why I went for that mobo. As for brands, Gigabyte, WD and a few other brands, have no problem with warranty and RMA here, as long as it was purchased new (or the S/N hasn't been asked for an RMA). When I bought the PSU I read in some places that topower builds for some other companies like Coolermaster iirc so that's why I went for it, so far I have never had any issue with it, it's been working rock solid for the last 5 years. I own a Hyper 212+ that, as far as I know, works with latest gen CPUs.
About GFX, I didn't know about that, I might take a look at last gen GPU, it also will make that current gen GPUs drop their prices, so I can get away with a better one.
Newegg is a great place for buying, but they don't make shipment to hotels, anyways I have friends living there, so maybe I can make them ship all the things to their place.
