OpenXenium VS spi2par2019

The OpenXenium modchip is an open-source project done by u/Ryzee119.

OpenXenium developed by Ryzee119 at github.com, and

Here you go https://github.com/Ryzee119/OpenXenium/blob/master/INSTALLATION.md Ryzee119's github for the OpenXenium. I've done a manual rebuild and used a board. If picking up a rebuild board, pre-tin all the points on the board before soldering it to the mobo. If not, you'll likely have a bad time.

This is fixable. OpenXenium + IDE to Sata adapter + Hard Drive is all that is needed. Not only will that get it working, but it will also be a massive upgrade to storage size and features available.

Thankfully these boards are open source and readily available! https://github.com/Ryzee119/OpenXenium

Yes, but not as an overlay on your TV. The info can be gathered from the LPC port and there's a mod, spir2par by Ryzee119, that displays temps and fan speed on an LCD screen. Since you have a Halo edition box, it probably wouldn't be a great idea to cut it up. But it is possible.

To use an inexpensive HD44780 LCD module with an OpenXenium modchip, you will need an SPI2PAR2019 too.

spi2par: lets you add an LCD screen to the Xbox that is controlled by software, but the interesting part is that this project allows you to get temperature readouts from the motherboard and display them on screen while you're in a game. So, while you're on the dashboard it can show date/time, or whatever you want. Then while you're in game, it switches to display the name of the game you're playing and CPU/motherboard temps + fan speed.

The spi2par2019 piggyback adapter you mention converts the OpenXenium's SPI signals into an HD44780-compatible parallel interface.

You'll need an spi2par2019 and HD44780 compliant parallel LCD module. An OpenXenium modchip too to mod the console will come in handy; however, I don't believe it's absolutely necessary to display the temps and fan speed on the LCD.
