My High Sierra (KL Rig signature below) up and running with new 10.13 download from App Store following tonymacx86's guide:

Many thanks TonyMac and everyone else posting helpful Clover and 10.13 info!!
Had several KPs trying to install 10.12 on this rig - bit bullet and did clean 10.13 install using terminal and latest Clover from Sourceforge per tonymacx86's link above. SSD working under APFS.
Several restarts would be an .. err ... understatement! Needed some manual restarts to complete installation process.
At one point screen displayed a MacOSinstaller dialogue - Disk Utility indicated about 5 GB stored on SSD. After installation completed storage was about 11 GB. Keep restarting until the Mac setup screen is displayed!
Decided against using MultiBeast for post install. Downloaded and installed Clover onto SSD and added apfs.efi and replacement config.plist files using tonymacx86's instructions as for USB. Rig boots fast from SSD.
Update - 11/29:
- (Re)installed OS 10.3.1 using HFS+J format for internal drive by editing minstallconfig.xml in vi after first install reboot
- Installed Realtek ALC 887 audio including Series 200 MoBo fix - credit Toleda
- Installed TP-Link N900 Wi-Fi PCI card - registered on first reboot - 80211.n @ 2.4 GHz
- No resolution to HD630 sleep/wake problem. This machine either runs or gets shut down!
- Working on installing EVGA GTX 750 Ti as a possible solution to sleep/wake problem.
This is a work in progress. Will report back on Nvidia GTX 750 Ti install, etc.

Thanks again everyone!!
