Do you need a server or a client?
Building a decent server within 20k is possible, but you would have to go for second hand components.
I currently use a plex server with an Nvidia 1050 for transcoding, and it works amazingly well.
The chenbro 2u with 8 3.5inch hot swap is 23k+GST at Arihant. Cant find anything cheaper in a rack configuration. Im having the same problems as @rock_ya_baby is :(
@vivek.krishnan says, i do have a 4 port GBe Intel Nic for sale. If your located in mumbai, i'd be happy to work out the details. You can PM me if your interested :)
If you dont mind me asking, what did you order?
I have been ordering lots of small home automation items from AE.
Also, what platform do u use for automation?
