I was lurking in this thread for a while after finding the BargainHardware listing on eBay. I bought one immediately after receiving the email from eBay. I wanted to buy more, but I was limited to a single purchase (it showed an error like "1 unit per each 10 days"). I made an offer of 149 GBP for one unit and added a note about the issue. An hour later, I managed to make another offer. I offered 100 GBP per unit for the remaining 6. In total¹, it came to almost 900 GBP including shipping and taxes.
Now, I'm looking for DDR4 LRDIMM, but the cheapest 512GB kit (8x64GB) I’ve found is around 600 EUR. The "sweet spot" seems to be 16GB RDIMM, but using 16x16GB lowers the speed and is limited to 256GB. Anyone knows where to get cheaper LRDIMM?
The main question is: why are they selling it so cheap? What’s the catch? As far as I know, the downsides are:
- Only 4x (or 3x?) NVMe slots
- No PCIe slot (needs a adapter)
- No PCie bifurcation (we can't add another 8x NVME)
- No BIOS/Firmware update
- Not from Dell, HP, or another known brand
- IPMI seems quite basic and not fully "plug and play"
- High noise (that is expected from 1U, not exactly true)
- CPU is 'fused/locked' to the motherboard (maybe we can't change the CPU too?!)
- No rails (previous posts seem to have found a compatible one).
What else? I don’t see why these disadvantages would drop the price to 250 GBP or even lower. The same seller is selling a
DELL R640 (with 2x 6138) and 64GB for 233 GBP, (price without VAT!), seems a good option too, but it's not EPYC.
EDIT:
¹ "In total" means the total of 7 servers (1 server in one purchase + 6 servers in another one).
