Need suggestions for new PC to run ASICs

[Morblias]

I have been running my HashFast on the RPi and it is unstable as shit. Not to mention they have not updated their firmware or cgminer version (using the default HF image). I am looking to buy something else to control these. I want it to be cheap, but not a "piece of shit toy"  

The RPi is a toy and a piece of shit. Why anyone would run thousands of dollars worth of equipment off it is beyond me. Toss it and connect your devices to a real PC or laptop.

I will be installing ubuntu on whatever I decide to buy. Would something like the zotac intel atom mini-itx work good? Is there something cheaper and better? I don't really want to spent a lot of money on a full blown new computer. Suggestions anyone?

I gave up on the Pi as well.  Waste of time and effort.

I have a single Bitburner Fury (50GH) running off a BeagleBone Black running Debian. 

Everything else, a mix of 10x Antminer U1, 2x Jalapenos, a NanoFury, and 5x HEX16A2 boards (total of 160GH) are all running off a Celeron Intel NUC.  It's got 2GB RAM and a 30GB SSD, and is also running Debian.  It also runs MinerDashboard and a few other bits and bobs that allow me to keep an eye on stuff.

I've also used one of the Foxconn Atom barebones, again running Debian.

All of them run perfectly.  If I could be bothered fighting with commandlines, I could probably get everything running off the NUC no problems, but I never got round to getting cgminer beaten in to submission to run everything stable.

The Pi is ok, but they are sensiteive to poor PSUs, and bad SD cards. Oh and avoid pluging/unpluggin anything from the USB while it is on.
There are better alternatives, but at a cast.
