Someone that goes by Worldwidewebbs (who enjoys making custom Xbox 360 faceplates as a hobby) currently has three Halo-themed faceplates for sale on eBay. Sure, you could purchase the official Microsoft Halo 3 faceplate, but why would you do that when you could have a one of a kind faceplate for a reasonable price? His faceplates are very simple but unique. Here are his current Halo-themed offerings.
Custom Xbox 360 Faceplate: Halo Master Chief in Gold

Features (from the eBay page) :
This Halo plate has the iconic image of the Master Chief, John 117, in the center of the power button. The color of the plate and MC is GOLD. The ring of light can be seen behind his head as a glowing green…. halo. Press his noggin to initiate startup sequence. This plate is TOUGH, but NOT INDESTRUCTIBLE. I would not recommend it for use in a home with children who don’t know how to handle fragile items, but I would have no worries about actually using it on your 360. The mem card ports, I/R window and USB ports work normally.
Current bid : $81.00
Auction ends : Oct-04-07 18:58:10 PDT
Update : This item sold for $122.50.
Custom Xbox 360 Faceplate: Halo Legendary Medal Copper

Features (from the eBay page) :
This Halo plate features the Legendary medal with Covenant Elite skull and crossed weapons. The color of the plate and medal is COPPER. The ring of light can be seen behind his head as a glowing green…. halo. Press his noggin to initiate startup sequence. This plate is TOUGH, but NOT INDESTRUCTIBLE. I would not recommend it for use in a home with children who don’t know how to handle fragile items, but I would have no worries about actually using it on your 360. The mem card ports, I/R window and USB ports work normally.
Current bid : $36.99
Auction ends : Oct-04-07 19:01:02 PDT
Update : This item sold for $52.
Custom Xbox 360 Faceplate: Halo Covenant+Plasma Grenade

Features (from the eBay page) :
This plate is inspired by the colors and designs of the Covenant Elite. The blue with orange accents, and light green in the center of the power button (I know the pic looks yellow, but it’s almost a lime green). The Covenant Elite plate also comes with an illuminated plasma grenade to amuse your friends.
Current bid : $57.01
Auction ends : Oct-04-07 19:07:28 PDT
Update : This item sold for $99.51.
He does have one more custom faceplate for sale right now but it is not Halo related. If you are only interested in Halo items, you can stop reading here. If you are a Star Wars nut like myself, you will probably love this last faceplate offering just as much as I do.
Custom Xbox 360 Faceplate: Star Wars Snow-Bunny Padme

Features (from the eBay page) :
This plate filled a need in my heart for SOMETHING that featured a likeness of Snow Bunny Padme from the episode of “Star Wars – Clone Wars.” The art style for the cartoon and figure is simple, so I kept the same feel with the plate, not overloading it with a bunch of unnecessary stuff. Press Padme to turn on your360 console.
Current bid : $19.99
Auction ends : Oct-04-07 19:13:47 PDT
Update : This item sold for $63.

I do too. l like the simplicity of the designs.
I wish I could see a closeup of the legendary design. It looks pretty awesome.

I think the helmet and the legendary emblems are clothing pins that were released when halo 3 hit the shelves.
