You get what you pay for. Yes ps/2 plugs are a thing of the past. Servers have for the last 5 or so years been usb only. Usually with a usb in the front as well as in the back.
There are usb/ps2 converters but usb/mouse is very cheap. Your adapter would most likely cost the same or more.
Lack of cd drive - sounds like you bought too cheap if you need that. Alternatively, pxe boot and install that way.
One nic is also quite common. It depends on what you need the server to do.

I bought a very cheap server yesterday - an HP ProLiant micro server for 160 euro (280 euro with 120 cashback, for some reason).
But I was surprised when I opened the box to find it didn't come with keyboard or mouse, and doesn't have the old keyboard/mouse sockets, but requires USB versions. Is that the norm nowadays? Is it possible to convert the old keyboard/mouse plugs?
Also there is no CD drive. But there are extensive instructions (on a CD!) about how to instal RHEL-5.5.
I'm not complaining, just surprised. I got it as a fall-back for my aging server. The ProLiant is incredibly quiet, at least by comparison.
One last thing - there is only one ethernet socket. This surprised me a little, as I can't see how it can be used as a server, without adding a second ethernet input?

while I'd agree with the rest of your assessments, on servers 1 nic is NOT that common, 2 or 4 built in nics is far more common.

Yes, on the larger servers. But micro servers often tend to have a single NIC

Neither are servers for €160! At that price I would expect to buy another card or just use vlans!

yeah, I looked up that server... its more like a SOHO mini-NAS, and in fact would be awesome if it just had hotswap trays for the 4 SATA drives, but no, they are not hotswap. its really more of a storage centric micro-PC, but it does have ECC memory. dual core low end athlon, 1-8gb ram, 4 sata bays, 1 pci-express x16 slot and 1 pci-e x1 slot, single NIC, onboard AMD video.

...... and, if it serves content to client PC's, it's a server ;)

The HP MicroServer does have hot-swappable trays... Great little box.

Ah, so I've made my system mad when sliding a drive out in the past and gotten lucky! Whoops! :)
Still, a slick little case...

While in most cases internal drives aren't considered 'hot-swap' since opening the case isn't typically a thing you'd think of when considering something 'hot-swap,' according to the libATA wiki at https://ata.wiki.kernel.org/index.php/SATA_hardware_features says that the AMD SB820M is AHCI, and supports hot-swap.
In most cases, true hot-swap trays and cages for SATA (like the ones for SuperMicro cases, to use one example) have no special 'interposer' logic like some hot-swap IDE and SCSI cages do, that does a staged disconnect when you turn the drive off with the key on the tray; it's a built-in feature of the drive (staggered contacts on the connector pair) and the controller for SATA, and especially AHCI. The 2U 6 tray SATA cage for the SuperMicro box I have has direct pass-through for all 6 of the SATA positions.
80-pin SCA SCSI cages (again, like the 6 tray Supermicro ones) can use the SCA connector's pin stagger to good advantage, and most of the time don't need interposer chips.
So you're not likely to damage anything by hot-swapping an internal SATA drive (as long as you issue the ioctls necessary, and things aren't mounted, etc), as long as you don't drop a screw on the running motherboard.....which is a real risk, by the way (yeah, I've done that, too). So it's not a good idea, but it could be done in an emergency, I guess (I say I guess, but in fact I have done this more than once, with a tower case where the drives were in easily removeable cages that didn't have screws to drop, and were well away from the motherboard or any other exposed energized components).
I've even done it with a laptop running on a liveCD.....

Well, I was hoping to connect one to my ADSL modem (non WiFi) and one to my router (LinkSys WRT54GL router).

thats what people said about ISA bus when PCI came out and replaced it.
btw, make sure you get a LOW PROFILE pci-e card for that thing. a standard height card won't fit either.

Because a PCIe x1 slot smokes your run of the mill PCI slot any day?

If you can't implement vlans, what about 'trunking on the cheap' with both subnets using the same switch? Not ideal, but doable.
