Apologies for the mess but am in the process of wiring in Fan Controllers & extra fans to cope with the Aussie Summer

You should be able to make out the 7 x Eyeboot USB Hubs each containing 49 U2's making 343 active ... the rest are currently spares!

2 of the S1's are on the second shelf - the third is just out of shot
The Falcon is on the bottom shelf

Cheers
