Like I told you in PM. It is not the right time to invest.
The price of BTC is going up after the little crash.
Best thing to do (that's what I am doing but you do what you want) :
Buy BTC (with ) -> Buy LTC (with BTC) at 0.03 -> Sell LTC (for BTC)at 0.04 -> Sell BTC at 1000/BTC (and above)
That way you can almost double your investment in 2-4 weeks.
When my trade is done I can invest 10-20 BTC so you can do whatever you want.
Do you know about watercooling ? It is very effective if you consider multiple big double GPU like 5 x HD7990 in the same circuit.
If the goal is LTC selling, then the sooner you invest in a rig the more Litecoins you'll have to sell!
Imho investment should be now, don't worry your spot is safe and even if You wanna invest a lot I might do solo rigs just for you!
Water cooling: Yes I do, Haven't used in a professional environment but I have used it in heavy duty gaming equipment. My room is cooled by it self so I'm gonna weigh whether to use regular or water cooling, might be able to reduce costs if plausible.
I'm writting down all options so that I might present them in full and get a decent general opinion on the best option.
