Many times I have shown my envy at the Custodians of the 40k universe. There are certainly times I’ve had to go into a bathroom to clean it and wish I had dreadnought armor to protect me. For those really big jobs, the Legio Custodes have the Telemon Dreadnoughts. You can order yours now from Forge World. They’re available both with and without arms.
From the website:
Fewer than a handful of Telemon Dreadnoughts are to be found within the ranks of the Legio Custodes, each intended to stand sentinel over its charges no matter the forces brought against it. The honour of interment in one of the few existing Telemon sarcophagi is awarded to only the most celebrated warriors. Rare is the foe who can stand against the array of esoteric, hand-crafted weapons that grace its chassis or the ferocious will and warrior skill of the master Custodian interred within.
