I'm selling my trusty desktop, if anyone is interested then please let me know.
Spec is:
CPU: core i7-3770S, 4 cores plus hyper threading (makes it look like 8 )
RAM: 16GB
Disk drive: 480GB SSD
Windows 10 Pro freshly installed (or if you supply something else then I can put that on instead).
The case is a very slimline desktop unit about 300mm square plus 60mm high and comes with a separate power brick (laptop style). In normal operation it's completely quiet, the cpu fan only comes on when image processing.
