Edit: My bad. I should have checked that you entered your PC's P/N down there. So it's the Tower PC variant, then. Well, as I said, you could fit the "15-in-1" card reader, but I forgot to mention you'd have to choose between that or your DVD drive.
Even though your EliteDesk 800 G3 Tower PC has a tower chassis, the 5.25" bay is vertically mounted, so there's room for only one of those. G2 towers had either a 3.5" bay alongside the 5.25" one or a blank spot for the SD 4 Card Reader depending on the model.
I'll leave the original reply "as is" for reference, though. Thanks.
Hi,
Sorry if I couldn't tell from your message whether you bought the Tower PC, Small Form Factor (SFF) PC or the Mini PC.
The first generation of the EliteDesk line of business PCs, as well as some of the workstations from the Z line, used to have the "15-in-1 Media Card Reader" (P/N F4N90AA) listed as an option part.
This part fits either into a 5.25" or a 3.5" drive bay. Since all SFF models, starting with G2, don't feature the 3.5" drive bay anymore, this would currently fit into the G3 Tower PC only. The only option would be the "SD 4 Card Reader" you mentioned for SFF PCs.
So, if you bought the Small Form Factor PC, there's an "SD 4 Card Reader" you could fit in there. You should look for P/N 759030-001. It looks like this:
From a quick Google search, it seems to be available at eBay and Amazon. It should be available at local PC stores as well and maybe even HP's Parts Store.
This is plugged to a blue USB3 connector on the motherboard (or a black one depending on the board's model, but doing so would dowshift the card reader to USB 2.0 speeds).
In any case, I'd advise having a technician assist you in determining whether your PC's motherboard does indeed feature any of these connectors and if the chassis would require any additional bezels, screws etc.
Finally, if it's the Mini PC, then yeah, you won't be able to fit anything into it, it's too small to accomodate any additional parts.
Hope this helps.
Regards,
Hito
