Laptop with USB cooling fan to run 24/7 with SB and other tools.
PC for general browsing.
i dont think thats a good idea..was doing that ruined my first laptop due to overheating,im in a airconditioned room and usb cooling with it too.
just purchase another pc,just a pc and remote control it. pc runs faster and cheaper than laptop,saves you money in the future if it ever breaks down
