GPU tiers — what we're asked for
The tiers we broker, top to bottom. This is a demand list, not inventory — RackMind holds no stock.
- 01
Tier 1 — B200 · B300 — Blackwell, current generation — Active demand
- 02
Tier 2 — GB200 NVL72 — full-rack Blackwell systems — Active demand
- 03
Tier 3 — H200 — 141GB, last-gen flagship — Lots we're originating
- 03
Tier 3 — MI300X — 192GB, AMD flagship — Active demand
- 04
Tier 4 — H100 — SXM5 · PCIe · NVL — Always sourcing
- 05
Tier 5 — A100 80GB · A100 40GB — the workhorse tier — Lots we're originating
'Lots we're originating' = a verified seller lot in process — seller anonymous, gear never in RackMind's custody. 'Active demand' = buyers asking now. 'Always sourcing' = send us yours any time.
Selling a fleet? Name the tier in your inquiry — it's the first sort every buyer runs.
Demand list
What we're asked for
GPU fleets and current-generation cards first. If your fleet or rack holds them, start with the part number.
- GPU ServersH200 / B200-class GPU modules · H100 / A100 modules · HGX baseboards · NVLink and InfiniBand optics & cables
- Compute Serverscurrent and recent Dell PowerEdge and HPE ProLiant servers · DDR4 / DDR5 ECC memory · Xeon Scalable and EPYC CPUs
- Top-of-Rack Switch25G / 100G / 400G switches · transceivers and DAC cables
- Storagestorage chassis, backplanes, RAID / HBA controllers (never drives — see the drives promise)
- PDUs & Powermetered and switched rack PDUs
- Patch Panels & Cablingpatch panels, cable managers, fibre and copper runs
- Rack Frame42U cabinets with doors, side panels, and rails
Drives are data-bearing media. RackMind never takes custody of data-bearing media — drives stay with you, or move directly to a certified processing partner for NIST 800-88 sanitization.
Seller intake
Inquire Selling? Send this.
You do not need a perfect spreadsheet. Send what you have:
- What it is — model and part numbers (for example: H100 80GB SXM5), per item
- How many — units, servers, racks
- The configuration — GPUs per server, CPU, memory, storage, and networking (NVLink / InfiniBand included or not)
- Age & history — when it entered service; new, used, or refurbished (tested, with warranty)
- Photos — the unit and its nameplate
- Where it is — city and state
- Drives — drives stay with you or go to a certified processing partner; RackMind never takes custody
- Title — that you own it, free of liens
- Your timeline — when it needs to move
Serial numbers come after a signed agreement — counts and configs are enough to start.

Filter the taxonomy by layer or identifier. The Qty and bulk control is the inquiry builder: selected lines travel into the Contact inquiry form. A part record is a reference, not an offer.
