Until recently, it was primarily twinks, nostalgics and RP'ers that lamented the loss of Naxxramas in The Plaguelands, but with transmogrification being announced, many people look at the sweet armor- and weapon models that were present, cursing themselves for doing SSO dailies and Gruul PuGs instead of making weekly Naxx runs in TBC.
But fret no more, for below is a guide to recreating your favorite Naxx look! Let's jump right in, shall we?
Every class had a 9-piece Tier 3 armor set, but for the purpose of transmogrification, these can be regarded as having eight parts, since rings do not show on characters. All of these sets have been recolored and re-introduced as 5-piece Tier 7 sets, with matching boots, belts and bracers available. Select items have different detail, but overall they look very similar. Exact replicas of all cloaks are also available.
Seven weapons and three shields have not been redone for level 80, but fortunately the most iconic and badass ones have been preserved. Most off-set armor pieces that dropped from trash do not have visual matches in the new Naxx, but since most people will opt for a complete set instead, these will not be touched upon in this guide.
Weapons and shields
The following is a list of all the weapons remade for Naxxramas in Dragonblight, listed alphabetically from top to bottom. These are exact replicas - no detail or coloration has changed.
Wraith Blade / 
Iblis, Blade of the Fallen Seraph became 
Grieving Spellblade
Widow's Remorse became Torment of the Banished
Toxin Injector became 
Nerubian Conquerer
The Widow's Embrace became Infection Repulser
The Hungering Cold became Slayer of the Lifeless
The Eye of Nerub became Wraith Spear
The Castigator became Maexxna's Femur
Spire of Twilight became Charmed Cierge
Soulstring became Accursed Bow of the Elite
Severance became 
Death's Bite
Might of Menethil became Demise
Midnight Haze became The Soulblade
Maexxna's Fang became Knife of Incision
Kingsfall became Anarchy
Harbinger of Doom became Omen of Ruin / Blade of Dormant Memories
Hammer of the Twisting Nether became Hammer of the Astral Plane
Gressil, Dawn of Ruin became Hatestrike
Claymore of Unholy Might became Claymore of Ancient Power
Claw of the Frost Wyrm became The Stray / Kel'Thuzad's Reach
Brimstone Staff became 
Sulfur Stave
This list contains all of the offhand frills and shields. Wands have been packed into this section, as they serve as more of a "stat stick" than as an actual weapon.
Sapphiron's Right Eye became Scepter of Murmuring Spirits
Sapphiron's Left Eye became Watchful Eye
Noth's Frigid Heart became Urn of Lost Memories
Gem of Nerubis became Matriarch's Spawn
Digested Hand of Power became Surplus Limb
The Face of Death became The Skull of Ruin
Shield of Condemnation became Aegis of Damnation
Wand of the Whispering Dead / Wand of Fates became Contortion / Plague Igniter
Doomfinger became Fading Glow / Wand of the Archlich
Of course, a few weapon models suffered the "No Longer Available to Players" fate. Among these are the downright silly such as the Homer Simpson shield, as well as the undeniably badass, an example being a mace from The Four Horsemen.
Those we mourn
Soulseeker
Nerubian Slavemaker
Maul of the Redeemed Crusader
Those we don't
The End of Dreams
Misplaced Servo Arm
Hatchet of Sundered Bone
Shields
The Plague Bearer
Stygian Buckler
Death's Bargain
The
Ashbringer
Perhaps the most desired item out of old Naxxramas is the
Corrupted Ashbringer - the unique looks, the whispers from the fallen Mograine and an epic event in Scarlet Monestary makes this one of the most historic items in the game. It has been made clear on several occasions that Blizzard considers it a mistake to ever put a weapon such as this into the hands of players. The lore implications were too great, and it seems the move was retconned, or at least to some extent corrected, when it was revealed that Darion Mograine, son of The Ashbringer, obtained the corrupted sword after killing his father in Naxxramas. It has subsequently been cleansed and is now held by Tirion Fordring. An interesting thing to note is that in addition to taking on a darker tone and a skull on the blade, the sword grew considerably when it became corrupted, also reshaping the hilt (http://img204.imageshack.us/img204/5807/ashbringer.png).
