Ooer, lemme see, this is my e-Machines £100 snotter that I run my server on:

Nowt weird about the disks; standard SATA hard disk:

/dev/sda:

And some optical read/write thingy:

cdparanoia III release 10.2 (September 11, 2008)

Using cdda library version: 10.2
Using paranoia library version: 10.2
Checking /dev/cdrom for cdrom...
Testing /dev/cdrom for SCSI/MMC interface
SG_IO device: /dev/sr0

CDROM model sensed sensed: Optiarc DVD RW AD-5200A 1.05

Checking for SCSI emulation...
Drive is ATAPI (using SG_IO host adaptor emulation)

Checking for MMC style command set...
Drive is MMC style
DMA scatter/gather table entries: 1
table entry size: 131072 bytes
maximum theoretical transfer: 55 sectors
Setting default read size to 27 sectors (63504 bytes).

Verifying CDDA command set...
Could not find any audio tracks on this disk.

Unable to open disc.

..."integrated Intel graphics and sound, Atheros wireless, ATA disks, no other fruity hardware".

The Atheros Wifi is a Netgear card, by the way.

ETA: It seems that a pretty bog-standard installation (I've got Roundcube, PostgreSQL and Openfire packages in addition to the usuals, but they don't count for much disk space) comes out at a rather svelte (by comparison with OS X and Windows) 2.7 GB.
