Edit: missed the part you wanted a pc for regular use.
That's how I started, you can really just build any pc with a good gpu for this. CPU, mem, and ram doesn't really matter. If you want to game you'll want to atleast get a decent cpu and 8gb ram. You could even get a case/mb that will fit 2 gpu's if you want so you can add second card later, but if you plan to go beyond 2 you're probably best off just building a dedicated rig.
If you're willing to spend a little of money and want to go beyond cpu mining, you could build the barebones rig (PSU, MB, CPU, HDD, mem, risers, etc) and just add a pair of cards rather than 6 or more. Then if you want to continue all you have to do is just add cards as you can afford/want to. I'd just recommend getting a motherboard that will support at least 5 cards. For PSU you could start with a 750 and then add another 750 if you expand, i'd just look for one with at least 4 vga cables (EVGA 750 g1/g2/g3/p2 fits the bill). You can probably get everything but gpu's for $400-500 depending on part selection if you go this route, maybe even less.
Beware its addictive, i went from 1 card to 18 cards in 4 months lol
If profitability is not your concern and just for a hobby or a test
You could start mining at a low or no cost and just use your existing PC's, CPU mining at the most
Best gear always depend on your requisites
you may require:
- lowpower cost with a decent hash
- Higher Hash and dont need a low electricity cost
- Low price gear with a decent hash over a certain coin algo
- High price Gear with a decent hash with a wide range of algo
- Higher hash, Low power cost, High pricing gear with risk of low or "0" resale value
basically, mining is not a want to buy candies in a store and choosing with a best taste from other people then buy
you have to consider your own environment and own taste which suitable and defines whats best for you
At the moment it isn't the peofit it is just the experience.
I just want to try mining but currently I only have a laptop so I am asking what specs is good for mining in PC ,
Because I also want to buy a PC and maybe use it into mining in the future so I could save some money right now if I buy a mining pc rather than just a regular one then after a month or two I would get interested in mining then I would have to build another one.
Thanks for the suggestion I would look into it.
It is really helpful and thanks for the concern.
