MiniLab

Many 3D printers have their biggest axis at 250mm max (at least those of my friends that I asked). While you can rotate the print a bit to max out the space, you have to print pretty high which apparently can become unreliable.

I wonder if cutting 2mm on each side for 10" mountable pieces is fine. The mount holes are are 236,5mm apart (measured from the center of each). If they get printed with 8mm diameter, that's 244,5mm (+4mm each side), so there's only 3mm left on each side when reducing the total with to 250 (instead of 5mm at 254mm total). That seems pretty narrow but then that part is not the load bearing one. Any experience with this?

With the YouTube influencers making mini labs and mini racks big right now, I'm surprised there's nothing happening here.

But Intel partner are able to continue to build intel nucs.

I have a Dell Optiplex 7060 MFF that wont boot, according to the power LED flash sequence it has a faulty motherboard.

The motherboard has a model number of IPCFL-BS 65W.

It had a decent i7 processor so I removed it and put it in a lower spec 7060 that I bought, I then installed the i5 from the other 7060 but it still wouldn't boot, no surprise there!!

I suppose I can do one of the following:

• sell it as is for spares or repairs on eBay (the CPU (i5-8500T) has got to be worth at least £30 on it's own)
• get a replacement MB from eBay or an AliExpress clone
• try and work out what has failed on this MB and fix it (this is way above my skill level)

Anyone have any other ideas or suggestions?

This is a great article about just how powerful these MFF PC's can be upgraded to and that you don't always need a rack mount or tower server!

Hi All,

Thought I'd add a quick post on how simple it is to add a 2nd NIC to the Dell Optiplex MFF PC's.

The unit I bought came with a wireless M.2 card and antenna and also an extra Display Port in the accessory port. I didn't need either of these so I removed both.

I then purchased this M.2 wired NIC from Amazon, I was too impatient to wait to get a slightly cheaper one from Aliexpress!! LOL https://www.amazon.co.uk/dp/B0B6ZVRNQ1?psc=1&ref=ppx_yo2ov_dt_b_product_details

Installation was really simple, I just had to ensure that the ribbon cable was laid as flat as possible so that it wouldn't interfere with the SSD and caddy. https://i.imgur.com/lt5Zgs5.jpg

I used two plastic bolts and nuts to hold the NIC port in the accessory port hole, it's not a perfect fit but it is secure enough.

I'm going to use this server as a pfSense router running in a Proxmox VM so the 2nd NIC was important.

I had some fun getting Proxmox and pfSense to see the 2nd NIC, but that's for another post!!

Hi all,

Seeing as I created this community it seems only fair that I kick it off with details of my Mini Lab!! LOL

Instead of them just sitting on top of each other I took inspiration from another user and built a custom rack using 2020 aluminium extrusion and 3D printed parts.

These are the specs of the servers

Pictures - https://imgur.com/a/d950ydM You can see most of the services I'm running in the Proxmox cluster screen shot, but I'm also running these in the CT called "docker-test"

• Docuwiki
• Heimdall
• Homeassistant (test env)
• Nextcloud (test env)
• Nginx Proxy Manager
• Portainer
• Overseer
• Pi-Alert
• Uptime Kuma

My "Holden" node currently has nothing running but I intend to use this node for Plex and the *arr's suite using my TrueNAS as storage for the movies & TV shows instead of the local storage.

I also have a a Dell Wyse 3040 that I've installed Proxmox on and this runs my instance of OpenVPN when I 'm away on holiday so that I can shutdown all the servers but still VPN home.

I've uploaded the print files to Printables - https://www.printables.com/model/499181-mini-lab-rack-for-dell-optiplex-mff-servers in case anyone wants to use them for something similar.

Also, it's quite heavy so I've had to relocate it from on top of a utility room wall cupboard as I wasn't convinced the cupboard brackets would support the cupboard, it's contents and the server rack!! LOL
