Shameless plug: I have a pile of 6TB Toshiba 7200rpm SAS drives that came from a Dell server and are in good working order. Looking to send them to a loving home. They should work well in your server. PM me if interested.

eBay or Amazon

RAM can be bougt used on ebay. I recommend buying SATA drives instead of SAS drives if the system supports them. They are a lot cheaper.

I have loads of 8GB modules from DL380 machines if you are UK based?

I may have some. I’d have to check.

What is that FlexLOM card? It looks like a 530FLR dual-SFP+ module, which is a bit of an upgrade from the standard, plus maybe a 331T in a PCIe slot?

I think I have a bunch of 4GB or 8GB *ECC DDR3. Post what you need, I shelved it years ago. If you’re in the US I’ll give you for shipping.

I would look for things on ebay. Google the model and find the type of RAM it needs. Same with disks. Disk drives are pretty universal, as long as you have the trays needed for that server. You either need 2.5 or 3.5 inch SAS drives. I can’t tell from the photo. If you don’t have the drive trays, make sure you get trays for your drives from ebay too. SATA drives will also work, but you’ll have better luck with SAS drives since they’re enterprise spec and tend to be more reliable and last longer. With RAM, the only thing that’s really different from desktop RAM is that you want to make sure you get ECC(error checking) for a server.

It’s fun to roll the Aliexpress dice for homelabs. Worked out great for so far.

I’d be hesitant to do that with drives and I’d attempt to use consumer drives.

Get the fan mod for the BIOS, your ears will thank you

Is it worth the electricity costs?

Do it eBay my friend.

From this angle, that looks like a DL380 G5. It’s not worth buying parts for. But if you must … EBAY, of course.

If you’re in Canada, look for ANK servers, on Ebay. Easy to deal with, and lots of parts for this sort of server.
