The main concern would be with the PSU, you'd need about 650 watts (or more).
That PC link refers to a tablet and not a desktop PC. At best, all i could find is http://www.gigabyte.com/products/product-page.aspx?pid=4352#sp
for the A6-5400k CPU, the motherboard GA-F2A75M-D3H which has only 4 slots for ram so how do you get 6gb of ram in 4 slots? Perhaps 2x2gb and 2x1gb of ram and this could cause a bottleneck effect especially if the ram are different speeds, timings, and voltages.
