5 4U servers using 25 AMD GPU's...Using 7kW of power. Not to mention the fact that it points out another of antique Windows XP failings:

In simpler environments, such as Windows XP, which uses LM that converts all lower case characters to upper case, the system will speed through all LM versions of a maximum of 2 x 7 characters in 6 minutes at a maximum LM performance of 20 billion hashes per second.
