You're going to want something to help your boys stay unique, but why torture yourself with extensive green stuff and plastic card work? There are a ton of good plastic boxes out there that can lend a serious helping hand to your forces. While there are metal offerings as well, I'll be sticking with plastic, as it's more affordable, easier to located, easier to work with, and most importantly, can be bitz ordered.
Enough talk, let's get down to the goodies:
1: Warriors of Chaos
If you get only one box to give your knights a boost, this is it. This box has it all: furs, capes, medieval armor and weapons, giant shields, and all the correct proportions to mesh with space marines. Just one of these boxes has enough goodies to customize an entire army. Scrape off the chaos icons and you have a large assortment of shields to work with, which function as both storm shields or decoration.

2: Empire Flagellant Warband
There's nothing like a mob of crazed religious lunatics to bring out the character of an anti-daemon force. This box will give your Grey Knights that ancient yet powerful look that 40k is famous for. There's a lot of fire, and a lot of papers nailed to different pieces of lumber, two great things for Inquisitorial forces. The heads, while smaller than a space marines, are still suitably intense in their facial expression for a head swap. Be sure to leave a couple bodies in tact, as their twisted frames and contorted faces make a perfect base for a daemon host.Official Product Page
3: Black Templars Chapter Upgrade
This box will expand on the medieval theme that we will inevitably see in the new Grey Knight sculpts, but what really sets it apart is that it will do so in a harmonious way. Perserving the purity of the visual theme GW has set out is important to some. This box will enable the hobbyist to add without having to break away from the strong medieval theme of the Grey Knights. This is the ultimate offering for those looking for a subtle way to mix in some variety with their army.

4: Blood Angels Sanguinary Guard
I was a little hesitant to mention these guys, because they are so overused at the moment, but the fact remains that this is a beautiful box. I see this box actually forming a lot of individual models (ie: librarians). I don't think the highly stylized armor will fit with the normal troops, but when you need to make a single character who really stands out from the pack, this box presents a potent solution. The angelus pattern bolter can easily be swapped for a storm bolter, and the blades of their weapons will convert nicely to nemesis weapons of every type.Official Product Page
5: Space Marine Commander
This box is practically required for any power armor army in the game, irrespective of chapter or alignment. It's meant to be able to create a single figure with plenty of options available. This means you get some serious mileage from a single box, with unique heads, weapons, and armor options. Taken by itself, this kit makes for a great space marine, but dispersed among an entire army, it adds volumes to an existing force.

6: High Elf Phoenix Guard
It's all about the Halberds.It's entirely possible the Grey Knight power armor box will have the optional halberds included, but how many times do you want to have to paint the same 5 blades over and over again? Add some variety to your project with these weapons, oversized for high elves but just right for power armor. Beyond this is a good selection of capes that can easily be trimmed and moulded to fit any marine. Look for the wonderful helms as well, which boast some impressive ornamental wings, wings that could easily be clipped and used for power armor, or weapon hilts, or shields...

7: Empire Battle Wizards
This kit has so many cool bits that it belong's in everyone's bitz box, bar none. At a GW retail price of $22.25 US, it's also one of the most affordable options you'll find. Among other bits, you will get: a fiery sword, a torch perfect for mounting on a backpack, several staff heads (great if your terminators are taking warding staves), a giant scythe, some cool robes that can easily become capes and purity seals, and some faces/masks that are loaded with personality.

8: Vampire Counts Grave Guard
There is a new special character named Mordrack who can take a unit of "Ghost knights" to accompany him. These are described as a unit of spirit terminators who follow him into battle. It reminds me of the lost and the damned models; spectral marines wearing armor laced with bone and fire. So how do you take that idea and apply it to terminators? Get some armored skeletons of course!Throw in the nice great weapon blades to make nemesis falcions, and you're gold.

9: Dark Angels Veteran Marines
The Dark Angels box packs quite a conversion punch for your dollar. You get 5 robed power armor suits, some great accessories, and equipment chalk full of character, such as the power mace. You also get terminator pieces, so the box pulls double duty as you begin working on that squad of paladins (and you know you're going to).

10: Space Marine Command Squad
Based on what we've seen in the Grey Knight rumors so far, there will be a use for every piece in this box, especially the company champion. The apothecary will make for a good conversion on the paladin terminators, and the standard can be added to any squad, or even function as a banner for a dreadnought, tank, or dreadknight.Official Product Page
