Approximately whatever a F5, F4 or Aleph would cost, plus the cost of the Jensen transformers... Which will probably be $35-45 each.
Chassis, and to a certain extent PSU is always the biggest cost, and also the biggest variable. There are chassis from China for $100 that would work. (Not counting the $80 for shipping it ...) There are people who can build amazing things our of heatsinks and some angle bracket, and there are people who will buy the wonderful Deluxe chassis from the store.
But If you forced me to throw some numbers out, I would estimate the following -
$120-170 for the PSU including PCB
$100-150 for the amp circuit with transformers and PCB, maybe more depending on were you source the Jfets
$25-100 for all the random little stuff that you never think about but goes into the amp
+ Chassis
Again, that's just an estimate. There's a lot of variables and it will be different from person to person.

Absolutely. The responses gauge the initial rush.
The PCB will probably be about what the other amps cost, $25/stereo pair or thereabouts. No idea yet on the transformers. Yes, they will work with the SemiSouth parts, the bias voltage needs to be a bit less, that's all
Here are some sound description, but needs an F6 description.

The 6moons review compared the SemiSouth version, IIRC, to the SIT2 amps.
6moons audio reviews: FirstWatt F6
"Where the SIT2/F6 were identical twins, the M2/F6 mere brothers possibly from different mothers, the F5 and F6 were twins sharing a womb but not the same huevo."
