I actually thought about ordering an old blade, but decided against it because it just seems like a giant PITA to get working.
Basically, for an old blade, the user needs to:
- Hack up an ATX power supply to power the blade.
- Come up with some sort of mounting solution for the board.
- Supply your own fans.
- Connect and config via an ethernet connection.
- Run a stratum proxy on a host computer.
Basically, running at 13 GHs with an old blade seems to require a bunch of kludges.
Hopefully, with a new blade you'll be able to connect to a computer via USB, connect the blade to a power supply using a standard connector, fire up cgminer and mine away.
Am I expecting too much?
