Basic & Cheap 24/7 PC

  1. Looking at a $300-$400 budget PC to have running 24/7. It's sole purpose will be to have PoS Crypto wallets running. The wallets don't require a whole lot of computing power so the PC would be similar to building a basic HTPC or very basic teamspeak server PC.

    I'm looking for efficiency and with the wallets running the PC would be next to Idle so I'm assuming the TDP would be 20-40w which is about $250 a year to run it.
    Here are the components I'm looking at, also I'm looking at getting a case with a PSU included to save costs however I am open to suggestions of purchasing a separate PSU if it's recommended since it will run 24/7 even on idle.
    CPU - Intel Celeron G3930 LGA 1151
    Mobo - MSI H110M VH Plus mATX LGA 1151
    RAM - Crucial 4GB DDR4 PC12800 2133MHz CL15
    HDD - Western Digital 1TB Red 3.5"
    Case - Aywun 108 Micro-U3 with 420W PSU

    I'm also open to 8gb of Ram, I opted for a NAS over an SSD since it will be operating 24/7.

    Open to suggestions and changes and also any advice, also read that Linux would be a great OS over windows however I've never used Linux.

    Its a good build but you think too limited and are weary of the price tag.
    4 watts higher and your electric bill will still be fine, also if you plan to do medium high gaming.
    Having more speed for say over watch, gta 5, final fantasy or any other good old fps online games will help.
    I suggest when you have more money later on get a 16gb pair of ram (8gb) per stick it will help with windows.
    Better hard drive than the red version, the red version is geared more towards security and most businesses will use that.
    A quick warning do not buy computer cases with psu already installed in them from manufacturers.
    Its not a great idea if the psu blows out or dies taking out the whole system by accident.

    Before you get upset hear me out first, I know you want a computer and pretty badly at that.
    I was in your shoes like this a long time ago its better to get higher end parts you can afford.
    Store up money for parts later on and build the machine once you have them all.

    All of those parts I recommended have really good warrentys if something happens to it and you did not abuse it incorrectly.
    Those companies will replace it once they verify that with a digital receipt from newegg/ or etc.
    You will need a gpu but that can come after thanksgiving or newyears eve once someone else gifts you enough money.

    I think you may have misinterpreted my needs.
    I already have a gaming desktop which is VERY capable and only needs a gpu upgrade.

    This PC will be used PURELY for minting coins which only requires the wallet to be open 24/7 and nothing more. I need the wattage to be as low as possible so that means no graphics card is needed and dedicated is enough. Also I read that NAS drives are fantastic if you plan on keeping the computer running 24/7.

    The PSU part I will dually note and might invest in a cheap case with good airflow and a quality 400w or 450w power supply unless anything lower is available?

    Sorry if I mistook your first reply as a new build, but still those parts minus the ram I selected would be great for your build.
    For your mining system I would recommend atleast 500watts, since you won't be doing any major with it.
    When mining at 3.0ghz on that celeron or pentium cpu I recommended it'll draw out 100-200watts daily. :/
    Mining is similiar to F@H so it can be fun at times but costly especially when you get a 400 electric bill in the summer and halfway through winter.
    I would suggest you get a good gt graphics card with good memory it'll help with mining.
    Taken from 2010 this is what you will be dealing with when you attempt to mine coins.
    This enough cuda cores to do a good job at mining and it doesn't cost too much at all.

    PoS is different to PoW. With Proof of Stake it's essentially like owning a stock and receiving a dividend, the more you have the more you receive. PoS does not rely on high end components however it does rely on a 24/7 running PC to have the wallet open to use your coins to "secure" the network. I don't need anything powerful but I do need extremely reliable and efficient to keep the PC running 24/7 at next to idle. Hope this helps and thanks for the help.

    Thats not going to cut it for mining coins, this is why he is doing a custom build.
    Please read carefully before responding back:
    If I wanted to I could mine coins during the day however it takes too long and I need my pc.
    I don't feel like burning out my haswell 4570-gtx750 ti card.
    Just to have 350+ electric bill facing me at the end of the month.
    What parts he chosen he could mine coins during the day in a small office or somewhere in his home with good air.
    His mining machine will be compact and shouldn't make much of a peep.
    That biostar motherboard/amd chip wouldn't last for very long and they are slow for doing jobs like this.

    Its costly just to make a block of bitcoins but if it has really good value afterwords.
    By all means go ahead and mine.

    I believe that you may be the one who needs to read carefully.
    What the OP is looking to build is a Proof of Stake (PoS) mining PC, not a Proof of Work (PoW) mining PC. PoS mining isn't your traditional, "run my system at full load" type of mining. PoS mining is based on how much of the currency the person owns, not their computational power.
    Here's a link if you would like to find out more about it:

    TLDR: This isn't your standard work horse mining. All that the OP needs is a low power PC that can stay on 24/7.

    Consider buying a used laptop and replacing it's thermal paste for a new one and replacing battery if it is not good.
    This way you have everything you need - compactness, built-in PSU, power efficiency, low price, ability to replace most parts if they fail and even a built-in monitor, speakers, you can mount it on a wall/high under ceiling/ in cramped space... There is a lot of good in used laptops for such things.
