Rationalising my thoughts, what I think I need is the cheapest versions (inc 2nd hand) of the following:
PCI-E, DDR3 motherboard
Suitable CPU for the above
8gb SSD (ie the cheapest SSD I can buy)
Case - as
linked (£55)
Anyone got any of the above lying around?
The other components I already have are:
RAM - Will take half (4Gb) from my HP
PSU - included in case
GFX - card out of the HP
