They use more power than a Raspberry pi but they are fairly low wattage compared to a traditional desktop. I think their PSUs allow up to around 200 watts but typical consumption is going to be far lower (id estimate around 45 watts)

Something else to bear in mind is that the power on the Opitiplex is going to be more stable than the Pi. Pi will usually end up with under voltage issues depending on the drives used and auxiliary devices. With an Optiplex, you know there will be enough power to handle surges in use.

With an optiplex you give up the ability to have GPIO pins for things but if that's a desire there are ways to support that with breakout boards

Thanks so much! I can get a Lenovo Thinkcentre M900 / 8 MB / 256 Gb for next to nothing, think I’ll go down that route!

For your main drive you'll want a 1TB minimum (2 TB preferred) if you want to common support for..

- Full index Bitcoin Node

- Block Explorer

- Electrum Server for address lookups for your wallet.

2TB will be room to grow for about 5 years from now even if ordinals continue taking up space on the chain. Cost for those drives have come down substantially in the last year

Any preferred external hard disks or just any regular one?

With that Lenovo Thinkcentre M900, I'd recommend opening it up and installing a larger drive internally.

If using MyNodeBTC, you will need 2 drives total as its based on separating OS from Data and permitting reinstalls of just the OS with ease. So in this case, 256 GB would be overkill for the OS drive (good, you'll probably never run out of space for your log files!) and you can add a larger internal for the Data drive.

Performance will be much better with an internal drive connected via SATA cables vs conversion through USB 3 interface being external.

This unit doesn't have M.2 suitable for storage so it won't support the smaller NVME sticks. An internal SSD drive will be fine. I've used low cost TeamGroup brand drives as well as Inland from Microcenter, but if you want brand name, the Samsungs are popular.

If you haven't seen it already, here's a good video on a tech explaining the process of working on that particular machine so you can get an idea where everything is https://www.youtube.com/watch?v=SM264QmyZaY

i just realized these lenovo thinkcentre m900 models come in different form factors and your case (and the innards) may be different then shown in this video. The even slimmer case styles will be more limited on options and I'm trying to find that now

Tiny model https://www.youtube.com/watch?v=ZnjVSvGMtSE

Shows an 2.5" drive bay good for an internal SSD.

There is a M.2 2280 slot on this model

Until you have it and open it, you wont know if the 256 GB drive that comes with it is an SATA (more likely) or M.2 type. Whatever it is, you'll want to get the larger drive for the other type

Oh man this is so helpful!!!!
