its certainly going to be hard to get 100 followers this way   

Second answer is incorrect.
The name "Satoshi Nakamoto" is believed to be a pseudonym.
Also added couple of new questions

Some of the FPGA stuff on the market is interesting.
I doubt the claims some providers are making in regards to upcoming ASIC.

Honestly, your best bet imo is buying 7970's - they will pump out good hash, and retain resale ability should this all go to hell.
7970x2 cards have been seen in the wild tho, and 7990's should debut soon.

Specialized equipment will save you energy and pump out slightly more hash, but there is no secondary market for them.

*waiting for the 7990's myself*

No prob - and nothing wrong with building a 1 Gh rig for fun. Also, it might turn out that one can mine alternative cryptocurrency after ASICs come out for BTC (most likely alternative atm is Litecoin). But I wouldn't want to bet a 48 Gh farm on this possibility being profitable (or on the chance that BFL ASICs don't materialize). I think buying BTC is definitely a much better investment than mining right now. Prices may pull in from $11 near term (i.e. in the next few weeks), but ultimately (over the course of years) I think price goes much higher.  And the coming ASIC + reward drop 1-2 punch may be a catalyst that takes price quite a bit higher in the next few months. 

Welcome Darkzen. You do realize that BFL ASICs are supposedly coming, which means that 40 Gh can be had for $1300? If this does happen, GPU mining will become obsolete. Do as you see fit, of course, but this is a particularly risky time to be putting together a 48 Gh GPU/FPGA farm IMO.
