Those "mining starter packs" and "mining kits" on that page aren't for Bitcoin mining are they? Surely they must be for Litecoin or altcoin mining?
They can technically be used for any kind of mining but they are likely marketed towards scrypt based mining.
Well most of the cost of the mining kits is due to the multiple graphics cards so it must be for scrypt or altcoin mining since there's really no point in mining Bitcoin with GPUs anymore. I don't see any mention of Litecoin on that page however. Just Bitcoin. Weird.
It was on the Bitcoin landing page so obliviously people with some level of interest of bitcoin would be looking at it. Many people who are interested in bitcoin are smart enough to figure out that GPU mining is not advisable and that GPU can still be used with scrypt based mining (although not for long with new ASICs for scrypt).
