My setup has grown pretty crazily since I got my first miners in late November...
First, the main mining area:

Here we have 2 Jalapeños (running at 7 and 8 GH/s) along with 2 larger BFL units (running at 55 and 58GH/s)

This is all plugged in to a USB hub, along with 2 Block Eruptors going into a Surface Pro.
Let's start off and LOL at the fact that as of that picture I didn't realize the end-ports on that hub were power-only, no data, so the Eruptors weren't actually mining.
The Surface Pro is going to be replaced by a Raspberry Pi that I was using when I was still mining in my office. Sadly I don't have a WiFi adapter for it yet so when I moved the mine downstairs as I added hardware (due to noise) I had to swap it out temporarily. It'll be back to running things once I get it WiFi-enabled after the holidays.
Then the latest addition, back up in my office:

ASICMiner Cube running at 38GH/s, connected to a Corsair AX860i.
Upcoming changes:
One of the Jalapeños has just been sold off and shipped today, to be replaced by 2 more Cubes that should be arriving today / tomorrow!
From 15GH/s to approx 150GH/s (soon to be ~200GH/s after I get those cubes) in 6 weeks...
Yeah...this is going to be an expensive hobby

And no, I'm not worried at all about making my money back from all of this or hearing how I'm wasting money.
