Selection help for an isolated test network

I would like to ask for assistance for a work related project.
My end product test stations run a second isolated network (per test station, separate from the corporate LAN), in order to talk to Ethernet enabled devices.
Many years ago, I selected a Linksys RV016 to perform my functions within the test station.
However, this is a bit long in the tooth and there is a window to select new equipment.

My requirements are laughable, but the form factor messes things up.
Required:
- DHCP server - In hardware. This will see a lot of MACs across it, including blank MACs. One unit under test will be on each station, so blanks are temporary, until assigned.
- Ability to set the DHCP lease time to a small value. (5-30 minutes)
- Rack mount - 1U
- Gigabit - This is an actual must have, as a proto new product will not communicate unless linked at this speed.
- Currently need 7 ports.

Preferred:
- Internal Power Supply
- Similar price range - I believe we were paying about $400 for the RV016s, so anything in that range would probably be fine.
- No internal fans

It appears that any gigabit router would function for my needs.
It also appears that some managed gigabit switches have these functions.
Which way should I go?
Are there suggestions for brands and models?

Thanks in advance,
Jon

Any layer3 managed switch should do it. The reason for layer3 is typically layer3 devices have the DHCP functionality you're looking for. What do you mean by "blank MAC"? An all zeros MAC? Not many devices will like a all zeros MAC.

There are two options for "blank" MAC.
The truly blank MAC of 00:00:00:00:00:00.
There are some products that still are tested this way.

My other "blank" MAC, it is a product that comes with a partially pre-programmed to our MAC block. All products arrive with the same MAC and are then changed to real MAC addresses.
Example: 00:40:0A:FF:FF:FF, where the last three octets are changed during programming.
These would not trouble any switch or router.

So far, I have only found two viable units that meet the requirements.
These would be the Netgear GSM7224-200 and the Dell PowerConnect 2816.
The Cisco SG300-10 is in the right price range, but does not appear to have a DHCP server.
The HP 1910-16G and ZyXEL GS-4012F do not appear to have a DHCP server functionality.

What other companies have I missed looking at?

Any little home router can be a DHCP server, you could just plug that into the switch.

Why not just run this thing in a virtual environment? It can do all of this easily and you will not have to buy additional hardware.
