Want help looking at my mining options and which one to pick

[film2240]

I've been a miner since may 2011 when I upgraded my (then current) PC (before it was later dismantled,had parts sold off then rebuilt the PC from 2007 with old parts lying around) with a Radeon HD6950.Since then so many changes took place that I was forced to stop mining at the end of 2012.

After 2013 (break from mining), I started mining again because of all those other alt coins that flooded the market with easier to mine options available.Since I've been able to save up a fair amount now from doing odd jobs and selling stuff plus my mini businesses online,I'm now forced to take a look at other options for mining.

Since I've discovered a really easy way to flash miner pi so for a raspberry pi thanks to a really easy tool for the mac,I've been considering setting up a pi miner with ASICs because I can mine other Sha-256 coins with them and finally reduce the noise/power use of my mining operation as I need a sustainable source on income to finance other more important projects I have to maintain.I don't see this as a big money spinner as the difficulty keeps rising to ridiculous levels for Bitcoin.

However I'm stuck with which option to choose.Should I:
1.Buy an extender to use a 2nd GPU with my rebuilt PC for mining scrypt coins?
Or
2.Buy a raspberry pi,buy 2 bit fury ASICs,reuse an old smartphone charger,wifi dongle,SD card and monitor.Will also need a USB keyboard and mouse to run with it though plus USB hub.This will then mine all the Sha based alt coins.just need to know the OS that let's me mine those easily/easy mining pool.

As I'm really stuck on which option to choose as I want to see which is more profitable and focus my money on getting those sorted out,I'm asking the community here for help deciding.Thanks

I don't think any of the other SHA alt coins are profitable.  But, you don't need a monitor, keyboard or mouse for a raspberry pi should you go that route.  You'll need a powered hub though.

Also it probably won't save you much in the way of costs I can tell you that you don't really need a monitor or usb keyboard and mouse with the Raspberry Pi.

I managed to get mine set up without ever connecting it to a screen or input devices. It wasn't too hard.

You can download a linux distro like minepeon onto the SD card on your PC and mange it entirely over the net. If you don't like MinePeons web interface you can also administer it with Putty over SSH which is likely enabled by default in whatever distro you choose.

What's the energy use of a raspberry pi compared to an old android smart phone?

Raspberry pi only uses 2 watts.  Can't really beat that.  Plus the hassle of compiling for whatever processor your phone uses if it's not supported.
