I have a question! I want to play FTB or Tekkit, or semi-custom mod packs (A mix of the two). On my single player world(s), obviosly, when I log off, my chunks aren't loaded, therefor my quarries/machines aren't running. This is a problem for me, so i was wondering how I can solve my problem. I was thinking I could leave my laptop on 24/7 with an instance of the modpack running, in a singleplayer world. I would cover the overheating issues. I could also run server software on the laptop, also running that 24/7. These aren't ideal, my laptop has 6GB of DDR3, quad core A6-3400M processor, 640 GB of HDD. My other option would be to buy a serperate machine, to host the tekkit server, for me to play on alone. I would need to buy a cheap machine to do this, that would be cpable of hosting multiple worlds and mods. Any suggestions on what I should do? I don't want to pay money to a serve company, because that adds up. What should I do?
