[Linux-aus] What to buy?

[James Cameron]

An old faithful home system died.  Power supply.  Lab DNS, DHCP,
firewall, and a DVB-T recorder.  So sad, but hey, 11 years was good.

What is a reasonable replacement these days?  Requirements;

- will run Linux, customer installed,

- quiet; on a remote farm there's no traffic noise to mask fans,

- two ethernet ports,

- a PCI slot for an old DVB-T card, Leadtek WinFast DTV1000 T, cx2388x
  kernel module ... or advice on a replacement four-channel receiver.

Thanks!
