Honeycomb LX2 Parts List

Here are the parts I used to assemble my LX2 board.

• Teenage Engineering Computer-1 Mini-ITX Chassis
• LX2 IO Shield 3D model
• Shapeways 3D Printing - used to print the above IO model. I used "Black natural versatile plastic" as the material.
• Dust covers for the 10GBE ports
• Micron DDR4 ECC SODIMM 64GB KIT (2X32GB) 2Rx8 3200Mhz CL22 MTA18ASF4G72HZ-3G2B1
• KC3000 PCIe 4.0 NVMe M.2 SSD, 2TB
• SanDisk 16GB Industrial MLC MicroSD SDHC UHS-I Class 10 SDSDQAF3-016G
• Noiseblocker BlackSilentPRO PC-P - case Fan 80mm, this is the case fan
• Motherboard Northbridge Heatsink 2 Heat Pipe Chipset Cooling Fan Desktop Cooler
• Noctua NF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, Brown), this attaches to the heatsink.
• Thermal Grizzly Kryonaut The High Performance Thermal Paste for Cooling All Processors, Graphics Cards and Heat Sinks in Computers and Consoles (11.1 Gram)
• StarTech Dual M.2 PCIe SSD Adapter Card
• Kingston Renegade PCIe 4.0 NVMe M.2 SSD 4TB (SFYRD/4000G), secondary internal drive mounted on the StarTech card

A few notes -

• I also needed a screw for the M.2 slot and it did not come with one. I rummaged around my screw bin and found one but I have no idea on size/threading.
• I went with an industrial SDHC card since the firmware/BIOS of this board is loaded to the card. Just wanted to minimize future problems.
• It took a long while to obtain the memory as shipped from China. The DIMMs were identical in terms of part number but a memory check failed since the board didn't think they were identical. jnettlett on the Discord channel helped me sort through how to remove that code and recompile, which I did and now it works just fine. If you run into this problem just insert 1 DIMM, boot with it and install your OS, recompile the firmware, drop it on to your SD card, and then add the second DIMM.
• Note that even though they are ECC DIMMs I have not been able to get the actual ECC EDAC device driver working under the Linux kernel yet. I believe this means I still benefit from ECC support at the hardware level but can't instrument any of it via the kernel stats. This may just be me missing a kernel compile option somewhere, so I still encourage ECC if they are within budget and you can source the modules.
• I ordered the SSD directly from Kingston, which in my experience makes the RMA process easier if it ever breaks. Protip: never remove stickers from SSDs or vendors won't honor the warranty (looking at you Samsung, and why I don't buy your stuff anymore.)
• The Noiseblocker fan is the only 15mm depth fan I could find. You need 15mm to fit the space between the case and the CPU fan, anything larger won't work or I would have purchased a Noctua fan.
• The CPU cooler was the most difficult thing to source. Try googling for "PCCOOLER HB-802 Northbridge Cooler 2 Heatpipes Support 80mm CPU Fan Radiator Aluminum Heatsink Motherboard Cooler" or something similar. It comes in a plastic package with writing only in Japanese. But it did fit perfectly and I did not use any 3rd party buckles, the screws that came with it just barely fit the holes on the board. Note that this heatsink comes with rubber attachments that will hold the fan in place. The fan I attached to the heatsink is the 80mm Noctua model above. I finally found it on eBay after having Newegg and others accept the initial order only to promptly cancel it when the item was out of stock.
• The StarTech PCIe card just worked out of the box, no special kernel changes or drivers on RHEL9.
• I have one extra CPU cooler on hand in the USA because I ordered two from China. If you really can't find one drop a note to 'shox' on the Discord channel.
