but you can sell your rigs for at least 60% of original price, more money begin with but less risky

does it work?

With due respect you picked the WORST card to base your example on, as I clearly stated above. The R9 290 is the Absolutely WORST designed card when it comes to noise level as well as poorly designed when it comes to cooling. There is a reason my altered card is BOTH quiet and cool (13-20 degrees cooler than stock!!!). The R9 290 is made to run at 95 degrees (or should I say "withstand") as they apparently used the cheapest design possible - which is why they "made it to run" at 95°.

Alpha Tech can EASILY build a fairly quiet rig. The key is in the fans combined with an optimal cooling and air flow design. It is not rocket science and the work has basically already been done. (Just like the aftermarket R9 290 cooling system.)

In this day and age, there is NO reason to have a rig running above 20-25Db's, depending on the level of cooling needed (and perhaps if the overclocking is huge). If we start making these rigs impossible to
keep in houses, we do mining a great disservice imo.

Worse case scenario, best case scenario. I purely provided an answer to the question, it's neither right, nor wrong, it's based on my current setup and thats all. I'm running it in a rack in a data centre, so it's neither here nor there when it comes to how much noise it makes for me. Whilst there is every possibility to make a quiet rig, I still have to wear ear plugs in my server room.

Noise, size, neither are a deciding factor in my equation. It just needs to be built and work well.

On the day when this 5MH/s card could come to my house (3Q ), R9 290X price can be 1,5-2 times lower than now, and there could be new GPU cards much more MH/power effective. I'm not sure is it a great deal

Besides.... it's useless for the other purposes

How much energy and how many cards would you require to get 5Mh/s from R9 290 cards?
Answer - At roughly 870Kh/s it would take you 6 cards (roughly 350X6= 2100 bucks). 6 cards would use 1800 watts of energy.

So, by waiting as energy just makes it cost prohibitive where I (and many others are to Scrypt mine) I can get 5Mh/s for 1350 bucks and use only 80 or so watts of energy.
Of note, though I doubt it continues, is the LTC difficulty is falling hard. Due to Doge or?

Now, I understand that the above is not true for everyone but it is true for many. Also, there is no way I could either handle 1800 additional watts on my current breaker nor handle the
cost of upgrading each of those NOISY cards with upgraded cooling (as they are just no available, though I got lucky and found 1.)

Indeed, until the bitter end !
