No problem fitting your own laptop drive or larger flash drive.
All works well, Dual VGA, Extended Desktop etc, special HP VGA-video adapter for second monitor if needed.
The extension kit comes from the USA (EBay) includes PCIe to PCIe right angle & PCIe to PCI,
fan and serial 9 pin D, and 25pin ports.
Tested TT S2-3200 and 1600, fan needs moving a little for 3200 due to header at the top of the board.
Best Thin Client so far I have used to run demanding software, Tutioune, etc,
should be no problem with "new" usb Rx!
Have a 12v to 19v converter for using from the car, as now we have a fast Cpu they have gone to 19v

This will now be my bench Tutioune monitor and /P kit, with 12v Vga monitor for Rx,
and the Odroid U3, HVR 1900 and DATV-Express board for Tx

Will update as I play etc, pics attached, S2-1600 not included
