Service tag on the system should help, as its what Dell uses to keep record of parts etc.

We got caught out here with the change to 3050s from 7010s. None of the pile of drives we got fit!

If you can get the SN or similar from invoice, the 'view system configuration' is a good help

For instance, although our CTO  3050 is missing it, it shows what should be there. (The drives we had seem to be the 12 with blanks)

9.5 perhaps for the newer stuff?

Like this one? 

Thanks for the replies.

Can't look up serial numbers etc as not on invoice and the comp hasn't arrived yet.

I did see the dvd drive listed as 'slim line' so perhaps that means it is the 9.5 mm deep one. Pity, as the 12.7 ones are much cheaper, but not really a problem!

It is an ex-lease with SSD and I thought it would be tidier to put the SSD in the DVD tray and my spinner in the normal drive space. 

Guess I can wait till it arrives to measure it! 

Cheers.

If it's a 9020 SFF (not USFF) then it will be the same as in my image - 13ish mm, so 12.7 would be right. There is enough room to hide an SSD internally with the HDD still installed without using the optical drive bay.

Thanks for that. I received the 9020 today so ordered a 12.7 caddy, then I read your last post!

If you didn't use the DVD space, did you splice out the power cable for the extra power connector?

Must say this takes a LOT less space than the old banger!

Thought I would just insert my SSD (I have an image!) and see whether Win 10 would sort out drivers and indeed it seems to have coped admirably! The Win ver that came with the 9020 was OEM and my other one is retail so it is transferable. At this stage it looks good so fingers crossed! 

Impressed so far.

I have inserted the 1TB drive into the cage and there is just no space above it. Must be a fat drive! I will use the caddy for now but could splice into the power and poke the SSD in there somewhere.

I just used a SATA power splitter. Something like this. 

The Optiplex machines have IMO (along with the ProDesk/EliteDesk) been the benchmark for a business orientated SFF PC for years now. 

I ended up making my own by soldering a ground and 5V wire from a socket into the Dell lead. Only need those two for a 2.5 SSD as one can see in the DVD connection.

So, all good with SSD, TB spinner AND DVD! Anyone want a 12.7 caddy?😟 Never mind - all good.

But best part is just switching in my Win 10 SSD. Win 10 handled the drivers surprisingly well and it activated fine.

And, like you say wratterus, these are great value for money. I also bought an Elitebook 840 G3 for my wife to use. I was very impressed with this. Very thin and with 2560 x 1440 screen res. Much better than my 840 G1!

Cheers.
