Hello i m buying 3 dedicated server cpu and 1 gpu server dedicated tell me is this profitable i m new to this kindly tell me the minimum server requirement to bitcoin or litcoin
As this is the technical support forum and not mining support, I'm assuming you're asking the minimum requirements to run a full node; if you're trying to mine with them, you'll be lucky to get a few cents a month. ASICs are the only profitable method of mining at the moment, and even then it can be difficult to reach ROI.
For Bitcoin, you'll need a minimum of ~50GB disk space, as the blockchain itself is nearly 30GB, and at least 1GB of RAM if you want to be able to run anything else besides bitcoind (for reference, my instance of Bitcoin-Qt is currently using ~320MB of RAM). A fast CPU isn't too critical, but a >2GHz dual-core or above is advisable since they're relatively cheap.
I can't speak for Litecoin as I don't use it, but its system requirements are probably similar to those of Bitcoin (though it will likely use less disk space). You could run both on a Linux box with the specs I mentioned above without much difficulty.
