I have this unit in hand. This is NOT a pre-order.
You are looking at Avalon ASIC Batch# 3, 4-module bitcoin miner. Each module has 80 Avalon 256M Chips. Total 320 Avalon Chips, hash rate 88Gh/s. I received it on August 5th. It has been successfully mining at 111Gh/s and clocked at 350Mhz since then in a air conditioned room. Your milleage may vary.
Payment must be made on pickup in BTC or cash equivalent at Mt Gox weighted average rate. I can also ship for a reasonable price.
