I suggest:
mini-tower / half-tower
AMD 4 core processor with virtualization facility
(AMD are cheaper than Intel in Europe)
(if buying Intel get the virtualization facility)
8 GB RAM
motherboard
with PCI Express and 1 or 2 older pci slots
4 SATA (and 2 PATA (ISA) for any old drives*)
USB 2 or even USB 3
Ethernet controller
sound chips
DVD writer
500 GB SATA HDD
HDD caddy for easy removal of the HDD
* Some ASRock motherboard have it
The cheapest source is likely to be found on-line by Googling or looking
at a major web buying site.
Good luck.
