Long time lurker first time poster in this sub but I thought you guys might appreciate it.

Long story short: My gf wanted to buy me a 10" rack as a christmas gift. She tried to order it three times but everytime it broke during transport. Sad and angry she said the one sentence that started this whole journey: "Can't you just print one?!"

So I went online and bought some cheap 10u rack rails and started design a simple frame to hold them up but then I thought to myself "If I design this thing from ground up anyway why shouldn't it look nice?". 4 months and a loooot of iterations later you can see the result of this simple thought.

The hardware itself isn't anything special for the most part. There is only a pi4, a managed switch, the Tplink er650 router, a Lenovo Thinkcentre M710q and some patch panels. My isp router is mounted vertically on the back of the rack.

The panel labeled "Tower" houses a D1 mini esp8266 board. It provides an api to physically toggle the motherboard pins on my unraid system that is standing in the shelf under the rack (did not have any luck with magic packages and my system some times only boots on second try). The Thinkcentre is running the web app providing a nice gui to toggle the power button and allows for auto start/stop at specific times as well as start/stop/restart whitelisted containers on my unraid server. This also allows friends and family to easily start the server and containers (like gameservers) with just a few clicks. There is also a physical power button on the panel if I am feeling lazy and don't want to reach for the shelf under the rack 😅 Before you ask: Yes I used an eth cable and two diy motherboard pin breakout boards to connect the d1 mini to the server. That's why there is a warning on the panel.

So to wrap this up: I now got a fully custom rack, highly optimized for my usecase, looks cool (at least for me) and costs like 50 bucks. Whats not to love about that?😅

My latest build for CPU-based scientific computing workflows (quantum chemistry, monte carlo simulations, numerical integration). For these applications, it's hard to beat the price-to-performance of a dual Epyc 9654QS system.

However, since it runs 24/7 under full load right beside me at my desk, I wanted a good cooling solution. I came across the Silverstone XE360PDD by chance, but didn't find much about it online. I thought I'd take a chance on it as I was very pleased with the corresponding XE360-TR5 cooler on my Threadripper 7980X system.

Overall, I'm really happy with the cooler. I was surprised how quiet it is while the system is under full load. It is vastly quieter than the XE360-TR5 on my Threadripper system. CCD temperatures average around 68 °C with all cores boosting to 3.5 GHz. The only trouble I had was that it doesn't quite fit in the Silverstone RM52 case; it took a bit of swearing and elbow grease to mount it securely. I was rather expecting that the case and cooler, being from the same manufacturer, would be measured to fit.

Other than that the build went together painlessly, and everything works great. Here's a parts list, for those who might be interested:

• 2× Epyc 9654QS (2.15 GHz base, 3.5 GHz boost)
• 1.15 TB (24 × 48 GB) DDR5 @ 4800 MT/s
• Gigabyte MZ73-LM1 rev 3.2
• Samsung 990 Pro 4 TB
• Silverstone XE360PDD
• Silverstone RM52

Before and after 😁

I am not sure if I am doing anything wrong, so I wanted to do a sanity check with the wonderful people here on /r/homelab. Am I doing something wrong? Do I need to jam each hard drive into each slot instead of a careful slide? I tried swapping drives around, but they don't see to be showing up in my Unraid until I put them into this configuration you see here.

Maybe, the empty slots need more finesse when i slide the caddys in, but they feel secure. And its almost impossible for me to see the connection from the top. Its all blocked.

I have a total of 16 drives, so all 16 are working just fine, but if move ANYTHING anywhere, it doesn't get picked up in Linux/Unraid.

Anyone else have experience with these 4Us?

I got this off Aliexpress/Alibaba: https://www.alibaba.com/product-detail/4U-Rackmount-Server-case-with-24_1601197397354.html

Each backplane is working and has power. As you can see, each row has at least one hard drive that is working with power. And my unraid is showing all 16 drives working

So.. I've bought that mini pc some time ago, cool little thing tbh. Ryzen 5 5560U, meanwhile has 32GB RAM and 1TB storage, 2x 2,5GB Intel Nics. Not bad at all to use as a little Proxmox Homeserver. But the cooling was abysmal. Tiny heatsink and a tiny fan, and a fan curve that would just ramp up and down constantly. So i've decided to throw the tiny fan out, make a large hole in the Case (poorly), stick a 120mm fan on top and cobble up a pwm controller with an arduino i had laying around. And ffs it works 😬 Fan sits around 30%, temps are fine. I did not think it would work that well...

Next iteration will be to push temp data through the serial connection to the arduino and control the fan speed dynamically instead of with the Potentiometer.

Grabbed this r230 off eBay with an e3-1230 v6 32gb ram and had the caddy’s and HDDs, 256gb NVMe on pcie riser card for os laying around. Was excited to have this just for backing up my hyper-v vms in my home lab, now I’ll be packing it up as it’s a paper weight, won’t turn on. I think it damaged the motherboard. I just don’t understand why they wouldn’t remove the adapter before shipping to prevent this. Just pure lazy. Waiting for the seller to reach out.

As requested on my previous post about my 4-Bay design, I have adjusted both my old 8-bay design to facilitate the use of either the SFF-8088 adapter OR the SFF-8644 adapter as well as made modifications to my 8-bay to fit the cheaper SAS-747TQ backplane since the SAS-833TQ backplane I had used originally has blown up in price.

Parts List:

Supermicro Gen 5.5 3.5" trays (MCP-220-00075-0B) x8 ~$50 for 8 on eBay
Supermicro SAS747TQ 8-bay SAS backplane ~$35 on eBay
SFF-8087 to SATA breakout cable x2 ~$16 https://a.co/d/efNZnns

----OR----

SFF-8643 to SATA breakout cable x2 ~$10ea https://a.co/d/bQk5g9g
SFF-8088 to SFF-8087 adapter ~$30 https://a.co/d/c2u3VQA

----OR----

Supermicro AOM-SAS3-8I8E-LP SFF-8644 to SFF-8643 adapter ~$13 on eBay
Supermicro 1U PSU PWS-203-1H ~$32 on eBay

----OR----

Enhance ENP-7025B ~$35 on eBay
Molex Y-cable ~$6 https://a.co/d/cKoZu7M
120mm of your choice x2 (Noctua NF-P12 shown) ~$16 ea. https://a.co/d/45AMhLL
ATX power jumper cable w/ switch ~$11 https://a.co/d/5w77CnE (this required a tool to remove the pins from the connector to feed it through the hole ~$17 https://a.co/d/iTMzX6b , you don't have to get one like this, but I wanted the other pin extractors for future projects.)

Grand Total of parts: ~$210, could save $32 with some random 120mm fans as long as they can pull through all the trays.

For hardware needed:
M3*4*5 Heatset inserts x6 (when using SFF-8088 adapter, only need x2 when using SFF-8644 adapter)
M3*5*6 Heatset inserts x2 (for SFF-8644 adapter only)
M4*6*6 Heatset inserts x6 (for backplate)
M3*6 socket head screw x2 (for backplane)
M3*12 socket head screw x4 (Only need x2 when using SFF-8644 adapter)
M4*6 socket head screw x6 (for backplate)

Not much but it's mine

I’m looking for a quiet 1u power supply for bd795i se. I’ve been looking at FSP models on eBay as they’re plentiful but no idea what’s designed for servers and to run loud vs home office.

Need to suit ISTOVO A09 but haven’t ordered this yet. I also looked at CIT MTX-007b and MTX-008b but decided against these due to low 180w rating and a small intake on side panel that’s a bit small for the 120mm fan. I’m not stuck on the istovo and would ideally like something similarly compact but with a half height pcie cut out at back.

I've got this rack taking up space, if anyone wants it. Verizon doesn't want it and left it here. A uhaul with a lift is recommended.

28.5"w 75.5"h 25.5"d (no doors)27.5"d (doors). Weight: Heavy. On wheels.

The Beast

Specs:

• 200W unknown PSU (ATX 250PA from FSP GROUP INC.)
• NVIDIA GeForce GTS 450
• i5 3470s
• 2x 4GBKingston KVR 700Mhz

I'm new to this and want to use this old PC, it's from 2013 and don't know if it's worth the try.

Also, just in case someone here knows it, the only power delivery from the PSU is a Molex to PCIe adapter cable, and it would use the Molex from the end of the SATA cables, guess with how low W the components are it can sustain it, but I don't know if it's safe for the workload, or to run 24h although it would be idle most of the time.

Thanks
