Hi,
I'm looking to sell some of the equiepement from my homelab, and to be specifically: 1. Mellanox SN3700C, 32x100G switches. Model: MSN3700-CS2FC (P2C airflow), production date 2023-03-25 - they are with original package, I bought them few years ago and actually never turned them on. Technically they are openbox - outter box was opened by me, but the factory wrapping and seal on it is still intact. Asking price: 2500 CHF per switch, I have two of them.
2. ASUS W790E-SAGE SE Motherboard (LGA4677, Sapphire Rapids WS board, 6xPCIe Gen5 x16 + PCIe Gen5 x8 slots, 8 memory channels DDR5 RDIMM, etc.) + Xeon W5-3435X (Xeon WS 112L, 16 core, 3.1 GHz base, 4.7 Ghz max boost, overclockable, support XMP memory profiles) with the box and most of the accessories (for motherboard and I probably have a box for the CPU), with few extra VRM fans (Noctua 40x40x20mm). I've used that mb-cpu combo for t-rex load generator ("Generating 1 Tbps of traffic on a commodity hardware", Nog.fi 2025.06) Asking price: 1200 CHF
3. ASUS W790E-SAGE SE MB + Xeon W5-3435X, but this one without boxes and accessories and fans. Second combo from the same talk. Asking price: 1000 CHF
In addition for any of the ASUS W790 mb combo, I can give for free slightly broken Artic Freezer 4U-M - one of the screws there fall off, probably can be inserted back with right tool.
Optionally - I have somewhere chineese cooler for LGA 4677 (looks similar to Noctua NH-U12S DX4677, but has high RPM noname fans and called "coolserver m97") for extra 20 CHF. I might have some other LGA4677 coolers around.
4. ConnectX-5 MCX516A-CDAT (PCIe Gen4), in a box, with high profile bracket only (I think I don't have low profile, but I can look), flashed with latest available firmware from ~January 2026. Asking price: 200 CHF per card. I have two of those. Note: those were originally CCAT, but reflashed to CDAT.
5. Bluefield-2 MBF2M345A-VENOT (Crypto Disabled, E-Core, 16GB RAM, 1x200G - basically I used them in NIC-mode as ConnectX-6 Dx), 300 CHF each. I can sell at least 2 of them, probably more as I have spare cards that I don't use.
6. I can also sell (if needed) 8x16GB RDIMM DDR5-4800 for 2.5k CHF. I used those sticks in one of the t-rex machines during the tests as I needed some RAM but not much.
All bigger stuff is self-pickup at 8864 Reichenburg until ~05.06.2026, after that I would move to 8545 Rickenbach ZH, small stuff I can bring to Zurich HB at one of the days when I am in Zurich.
Price is negotiable with reason (e.x. if you want to get both switches and self-pick up before I move to a new place - I would gladly sell both of them for 4k total)
Small correction for the Bluefield-2 - exact model is MBF2M345A-VENOT_ES, they should have a 24.44.xxxx firmware flashed, which is one of the latest that was released, but I can check or update if needed. And I did a count - I can sell 8 of them, 300 CHF per card.
6 of the bluefields are also gone.
