TS-453A is fairly old NAS. It used to be a great choice, but now people choose the new model which is TS-453Be.CPU will not support more than 16GB of RAM on this model. You may need to think about Qnap TS-473/73e model for this. You could also install dedicated GPU for virtual machines if you happen to need this.The 53A could stream some of the 4K (H.264). Transcoding might cause troubles. But direct streaming should be OK.I hope this helps.
