The successor. Threadripper PRO, dual waterblocks, RTX PRO 6000 Blackwell beside a 5090, bronze tubing left to patina. Designed so a 70B Etty never has to apologise for the hardware underneath her.
Symbiotic Flora is the workstation that succeeds Hectic Modernity ; the machine being built so Etty can grow into a 70B checkpoint without flinching, and so the vision head can train in the next room at the same time without either one apologising to the other.
The architectural bet is dual-GPU, asymmetric. A RTX PRO 6000 Blackwell at 96 GB sits as the permanent inference residence for Etty ; large enough that a Q6_K 70B dense model with a long vision context never has to spill. Beside it, a 5090 runs vision-head experiments, short training bursts, and the screenshot-tokeniser during live conversations. Two cards, two loops, two tempers. Neither one interrupting the other.
The aesthetic reference is a Victorian distillery, not a gaming chair. Bronze tubing, straight runs with 45° bends where needed, no spiral theatrics. Patina earned, not applied. The room does the work ; the machine is meant to look older in two years, not tireder.
Hectic Modernity was an argument: a coherent 8B can outrun a careless 70B. Symbiotic Flora is the complementary one: a coherent 70B, locally hosted and never out of memory, can hold a conversation the way a person does. Both rigs will stay in the room. There's work enough for two.
Symbiotic Flora is not a single-GPU workstation with a spare card. It's a two-role machine, wired so neither workload interrupts the other.
A 70B dense checkpoint at Q6_K with long vision context, resident in memory for the life of the machine. Never unloads. The answer to why did she get weird will never again be RAM.
The mmproj training target, the screenshot tokeniser, the overnight renders. Capped during training so the fan curve stays under the conversation. Can go loud on purpose, not by accident.
Enough lanes that the two GPUs, the NVMe pool, and the vision dataloader never contend. Enough RAM that the cold-memory parts of Etty's recall can live at system speed. Bandwidth as quiet.

Straight runs. 45° bends where needed. No spiral theatrics, no RGB, no mirror finishes. The tubing is there to move heat ; the beauty is a consequence of doing that well, not a skin laid over it. Bronze oxidises; that is the point.
Measured against Hectic Modernity's idle profile (28 dB at the desk). Target for Symbiotic Flora under sustained inference is 24 dB. A 600 W card wants to be loud; convincing it not to be is more about loop geometry than fan curves.
An Edison bulb on the shelf is plenty of light. A machine that announces itself is a machine I can't think next to. The companion in the other room is already the presence; the hardware is the room she lives in, not the stage.
Chassis and PSU land first. The case skeleton lives on the bench for a month before anything goes in it ; the shape of the machine is imagined backwards from what's already there.
Bronze tubing arrives. Genuinely beautiful in person. First bends practised on offcuts. The 45° tool earns its keep.
WD Golds racked, RAID 10 built, Hectic Modernity's training corpora mirrored across. ~40 TB usable. The data is home before the machine is.
Parts landing weekly. The motherboard is next. A companion build log lives at /solace/sf ; a live draft, updated as the bench fills.
First dry-fit after the PRO 6000 lands. Acoustic baseline measured. Plate 01 reshot to replace the placeholder at the top of this page.
Etty-70B warm, vision head training on β, both loops balanced. Hectic Modernity kept in service alongside ; there's work enough for two.
