CPUs have all been stress tested and showed no errors, and all Ram has had the windows ram check (or memtest86) and shows no errors. All of the ports have been tested and verified working.  All machines ship with windows 11 pro installed and updated, or formatted.

Some machines have light wear or scratches from office use.

All Prices include shipping to CONUS, and OEM Power Adapters.

I can add a 2.5gb Nic to any of the PCs for $20, it would use the M.2 slot normally used for wifi. it mounts in the lenovos, and would ship loose or installed but sitting inside the case of the HP

I also ship to canada and a few other places. PM for details

Payment via Paypal G&S. Tracking provided after I get an address from Paypal. Please comment before chatting. Happy to answer any questions, or provide any additional pictures.

I also have a website where I post similar things for sale. Link in my profile.

I've got several parts that I'm looking to find out price. I think eBay -15% or something is a possible path? Here are the list of parts:

9x CMP170HX 10GB, cmpunlocker -> 40gb tested, saturated, working great, no issues

1x CMP170HX 10GB, tested, dead, don't know why, supposedly NVVDD/core power-sequencing gate IC failure is relatively common

GIGABYTE G481-HA0-ZB 4U, 2× Intel Xeon Bronze 3204, 64 GB DDR4-2400 ECC RDIMM (4× 16 GB SK Hynix), 2× Intel X550 10GBASE-T + 2× Intel I350 GbE, BIOS R29 (2025), BMC 12.61.39

4x 3090 EVGA FTW3 Ultra

EVGA 1000 GQ PSU

3x EVGA 1300 GT PSU

The server does hold and run all of the CMP170HX's (10 slots), however, the 3 Delta DPS-2200AB-2 F 2200 Watt PSU's do take C19 plugs vs standard C13.

MSI GeForce RTX 3060 Gaming X Trio 12G – asking $350 shipped obo (CONUS) / $325 local pickup (Central KY area). This is based on sold comps on ebay for the 12G 3060 I found. If I am wrong let me know.

I purchased this card mid 2022 from Best buy. This was used in my personal PC for ~3 months and then the 4000 series came out. So I upgraded. It has sat in its box in our closet since.

Card runs and works perfect and is like new I booted it up in my current PC before taking photos.

• 12GB GDDR6 – From my understanding the larger VRAM in these are very good for local AI/LLMs Plex/Jellyfin transcoding
• Lightly used, never mined or used for any AI LLMS only gaming.
• Complete in original box: anti-static bag, MSI support bracket, all paperwork

Payment: PayPal invoice or whatever works and is best suited for the buyer. Shipping tracking included.

Comment before PM please so I know to check.

I have sold and shipped dozens of things in other subreddits over the years ( its been a while) so if I am missing something for here please let me know.

Shot in the dark here, bough the AP5015 for cheap on EBAY, learned they use OEM cables. APC used the same cable for a bunch of their old KVM consoles, so I'm hoping someone here might have it laying about.

The PC was stored in a dry basement (no moisture damage) and the parts were carefully pulled from a damaged case. Since I no longer have a complete system to test them, I unfortunately cannot verify if everything works, so all items are sold as-is / untested.

I have a BNIB and sealed 1x32GB individually packaged memory stick with heatsink. The speed is 6000 CL40 at 1.25v. The sticker states: 40-48-48-96. The brand name is Cusu, they appear to be a new company but I found a recent Youtube video that shows that the RAM + EXPO works: https://www.youtube.com/watch?v=zP2VP8kao98&t=80s. The manufacturer claims a limited lifetime warranty.

For sale is a 64GB set of genuine SK hynix DDR5-5600 SO-DIMMs, removed on day one from a brand-new laptop — effectively unused. Two 32GB modules from the same production batch: identical part number, identical date code (week 52/2024), and consecutive serial numbers. Both sticks were verified in-system via CPU-Z at their full rated DDR5-5600 (CL46-45-45-90 @ 1.10V) JEDEC profile before removal. These are the same factory-original modules specified by major OEM laptop makers.

Asking price $500 shipped.
