The age old question. The Antminer R4 is a step in the right direction with the quieter fans but it costs an arm and a leg. Are there any other miners that could be used to mine at home and give you an ROI that cost less than an R4?
Can you? of course you can. If you enjoy maintaining a noisy rig and constantly having to monitor it then yeah, go for it. But be prepared to lose money.
Unless you have extremely cheap electricity/free electricity that you can somehow obtain(hopefully legally), and you're not into mining because it's fun, but rather only for the profits, then no, it's not feasible anymore with so many pools operating and difficulty shooting up.
