The descriptions I add to transactions keep on getting lost.

It only preserves the most recent description. I am running latest version 5.15.

100 cables minimum, but really low cost.

Anyone want to chip-in for this? I would probably spend ages on ebay and bitcoin forums trying to flog off the other 180 cables. 

I would be fine with someone reputable taking over this group buy and doing an escrow.

All I am after is 4 cables for less than $120. 

[Expected stats]

Just another rate my rig before I buy and set it up thread.

Expected stats:
Hash rate between 2400 kHz and 2600 kHz
Power consumption about 20.544 kWh @ $5.5 to run each day

Outstanding questions:
Where did you guys get your powered risers from?
Do I link the GFX cards in XFire, or can I leave them standalone? (Naturally running headless on a flavour of linux)
