Well I decided to move my components from my 678 Case (that is very close in size to the LZ7 case) to my new LZ7 XTD case.
Components:
GIGABYTE X570 I AORUS Pro Wi-Fi Motherboard
Ryzen 5 3400G
Changed cooler/fan to Noctua L9x65 Cooler with NF-A9 PWM chromax.black.swap fan (L9x76?)
EVGA SuperNOVA 450 GM, 80 Plus Gold 450W, Fully Modular
Samsung 1TB NVME970 Evo Plus x 2 - one top & one bottom or on PCI slot card
Corsair Vengeance LPX 2x16GB 3200MHz Memory
Noctua NF-A12x25 PWM Fan Case Fan
Kingston USB3 SD Card Reader

I was a bit worried that the XTD case would be too large, but this was not an issue. The size increase is alright. I really wanted to have access to the MB without removing the PSU, and with more cooler height space and airspace within the case in general.
The Noctua NF-A12x25 is installed on the (GPU) side of the case where there is plenty of room for the 25mm thick fan.
I moved the 2nd NVMe drive to a PCI card slot from the bottom of the MB to see if this would be any cooler as it runs about 6 degrees warmer than the primary enclosed & fan cooled drive even with no HD activity - turns out it still runs the same 6 degrees warmer despite the case fan blowing directly on the back of the PCIE card.
I faced the PSU fan away from the MB which is why I ordered the new front ventilated panel that should be here shortly. The fan has yet to come on but I am not stress testing the unit at this time. The PSU has fairly short cables that improves the installation.
I could use a GPU panel blank.

Here are a few photo's.

I updated my build with the extended vented front panel, changed the case fan to a Noctua NF A12x15 fan mounted on the right side case panel and installed a Ryzen 7 Pro 4750G APU. The GIGABYTE X570 I AORUS Pro Wi-Fi MB had the F20 BIOS already installed so no update was necessary. Some updated photographs:

Ryzen 7 Pro 4750G APU only Temp & Time testing with HW Monitor in LZ7 XTD on Gigabyte X50-1 Aorus Pro Wi-Fi MB
with Noctua L9x65 with A9x25 CPU cooler fan and Noctua A12x15 case fan

Blender Classroom Render & Unigine Valley
Render Time 10:32.92
Max Temp - NOT Delta / Room temp was about 20C
System 1 - 46C
CPU - 77C
VRM - 41C

Blender Classroom Render Only
Render Time 8:49.11
Temp - NOT Delta / Room temp was about 20C
System 1 - 44C
CPU - 77C
VRM - 39C

Both CPU fan A9x25 and Case fan A12x15 ran at full speed as temps went up.
I set the case fan to read the CPU temps for a quicker response as there is very little change in System 1 or VRM temps for the case fan to respond to.

A separate test using only the CPU-Z stress test with full speed or reduced 85% case fan speed:

Temp - NOT Delta / Room temp was about 20C
Max Fan Speed
System 1 - 43C
CPU - 77C
VRM - 39C

Temp - NOT Delta / Room temp was about 20C
85% Fan Speed
System 1 - 44C
CPU - 78C
VRM - 40C
