Need help with HTPC Hardware/Software Config

Hi,

This is my first post, so please excuse and advise if I posted to the wrong forum. I am interested in building an HTPC based on KODI with PVR capability for recording OTA content from terrestrial antenna. After several hours of research, I’ve narrowed down an initial configuration:

HARDWARE:
HTPC: ASUS Chromebox2-G095U
OTA Tuner: HAUPPAUGE WinTV-DualHD Dual USB 2.0 HD TV Tuner 1595
Storage: SEAGATE STX-GFD-USB3 2TB Drive

SOFTWARE:
OS: LibreElec
Frontend: KODI
PVR: TVHeadend

My main question is this: Is there enough “horse-power” in the ASUS Chromebox to use it as both a KODI client and to host PVR software to record content from the USB Tuner and store it to the USB external drive? Also, I would like to subscribe to a legal iptv service if the box can support that too. I have not purchased anything yet, but I have the USB drive from another project. Any advice is welcomed, as I am definitely a newbie and would like to get it right the first time if possible.

Thanks,
Dave
