I had to add a Display-port to DVI connector on one monitor, and can't use the add-on card in Windows 10. not supported for dual monitor. Added a solid state drive, TPM encrypted everything, works great. Win 10 Pro version, so Remote desktop available. very happy. Added better  WiFi adapter.UPDATE: Since I purchased it, I've added an Display port to HDMI adapter and used the onboard VGA for the second monitor. the expansion card only works properly in Windows 7.. and this has 10 x64 Pro. Installed a SSD drive, and it works great. Maybe I got lucky with clean monitors and case. wireless very disappointing. Added an AC1200 USB adapter. Bluetooth was ok. Just wish it was a complete and tested package.. Technicians delight, perhaps...
