Custom ASIC Minging Rig - Hardware?

[uMMcQxCWELNzkt]

I would like to get some advice on the type of rig spec required for a high performance mining rig functioning as a viable(profitable) option for the next 2 - 3 years. I have lots of design concepts and a programmer friend keeps trying to talk me into developing a unit, I did go through a phase of it would not be profitable but I am entertaining the idea for the moment as I hate to turn down ideas. I would really appreciate a break down of the hardware components necessary to contruct a unit.

^{Yes I am aware of the difficulties of having the ASIC chips and PCB boards manufactured.}

Send BFL an email im sure they will provide the info to build one in an hour for under $300

Right now your choices are:

1. Buy an Avalon preorder and hope it shows up before ASIC Miner et al. renders it nigh unprofitable
2. Buy a BFL preorder and know it will never show up before the above
3. Buy a blade from ASIC Miner and be content to recoup/profit from your fiat investment knowing you almost always would have made more buying BTC directly
4. Buy ASIC chips directly from Avalon in a group buy, or if you have 1,000B you can buy them yourself and then have them assembled in another group buy, hoping you don't get ripped off/held up/board malfunctioned/lemon/design problems every step of the way.

Option 4 is hands down the most affordable and will produce the greatest return, but you won't see a miner in hand for 3-4 months. If you want one in hand you pretty much have to buy a blade from AM right now.
