The HP t5730 I have (model: HSTNC-003-TC) was manufactured in March 2009. When I first unpacked it it seemed a little large to me. In fact this is an optical illusion and it's almost the same size as the Neoware Capio 620. The photograph on the right shows it with a Neoware Capio and Wyse SX0 for comparison.

Power Supply

The unit requires a 12V supply. The coax connector is 5.5mm/2.1mm.

Expansion

(Click on the photo for a larger version.)

Flash: The Flash memory (top left in the photograph) is easily replaceable. It's a DOM plugged into a standard 44-pin IDE connector.

RAM: The RAM is a standard 200-pin SODIMM. The one fitted is manufactured by hynix and is marked: PC2-5300S-555-12. The part number is HYMP112S64CP6-Y5. (It's a DDR2 667MHz SODIMM). I have tried out a 2GB Kingston part that also worked. (KT833W39035). This is a low density (8 chips per side) PC2-5300 part.

In September 2019 I heard from Jeffrey who had recently come into possession of a 4GB Samsung PC2-6400 SODIMM. (M470T5267AZ3-CF7). He reports that this worked.

Note: As Jeffrey also noted in his email 4GB DDR2 SODIMMs are very expensive (which is why I have none to try out). Checking on eBay they are currently £35 or more. At that sort of figure you're better off buying a more modern thin client which will cost less money and will probably come fitted with at least 4GB of RAM.

CPU:. Tom Williams emailed me about the possibility of overclocking the CPU - something I didn't think was possible. However he persevered and emailed me again in June 2011 about this. Subsequently a chap called MoMo joined in. You'll find all this under the mods tab.

Compact Flash:. It turns out there is space on the reverse side of the circuit board for fitting a Compact Flash socket. You'll find this under the mods tab as well.

PCI-e: The board carries what looks like a PCI or PCI-e slot. This is used with a riser card and expansion housing that doubles the width of the thin client. The expansion module provides a 1x PCIe socket along with a serial port and a parallel port. Obviously connections to the latter must pass over this interface. Unlike the t610 this socket is completely non standard and any attempt to try using anything other than the standard HP riser will end in disaster. (Thank you Dominik for checking this out).

Wireless Option.

There is a factory-fit wireless option available. The antenna sits at the top rear of the unit.

The socket for the antenna is fixed to the top rear of the t5730 chassis. The cable is routed through a hole in the PCB to the rear of the circuit board.

I didn't dismantle my t5730w as it's a fairly extensive job to get to the rear of the motherboard. However I did have a motherboard that I'd removed from a dead t5730. In the photo you can see the area on the back of the motherboard under the corner carrying the IDE interface.

At the top the board is tracked to take a Compact Flash card socket and below that it is tracked for a mini-PCIE interface. With the t5730w this socket is fitted along with the wireless card.
