as for the case i have core v1 (mini itx in core XX line) and i am very pleased with build quality and assembly options it offers.
if you can handle X5's dimensions (its foot print is bigger then standard tower) and price you wont sorry for your choice. the only "negative" thing about it
IMO is that it comes with 120mm front fan instead of 200mm one. i am planing to move 2 of my home pcs in 2 stacked X5's but later cause i have to make some space management at home before i can use em the way i'd like. now i have cm trooper and haf 932. haf is good case with a lot of space and good air flow capabilities but its lack of filters cause it to dump inside every piece of dust in my home (despite everyday cleaning dust is part of my environment and is beyond my control atm :/)
