Iceriver KS7 Lite

t achieves about 4.2 TH/s of hashrate while consuming approximately 500 W of power.

With 4.2 TH/s at 500 W, the efficiency is roughly 119 J/TH, according to one listing.

• Input voltage: 100-240 V AC (wide voltage).

• Ambient operating temperature: 0–40 °C typical.

Yes  given its modest power draw (500 W), compact size and relatively low noise, it is quite home-friendly or suitable for a small mining rig setup in a dedicated area.

You’ll need a reliable 500 W circuit (plus margin), good ventilation (for the heat output), Ethernet connection for pool access, and room where noise/heat won’t be disruptive.
