Took a grand total of 30 minutes to take out the processor/HDD/optical drive from the Dell, it's now scrap. Also salvaged video card, i imagine i can sell it on for like £20 or so but I don't think anyone would be looking for it anyway, so i might keep it handy for troubleshooting or something. Can't think of any uses for it so far.
The windows ISO i got my hands on works... i tested it last night so that's made me a happy chappy, still need to buy windows (I don't like MS but I don't believe in pirating software... unless it's EA, I haven't forgotten CnC4 yet!!) but I can wait until payday for that (£100 of my pay already dedicated to it).
Considering going for this 2TB HDD: Seagate ST2000DL003 Barracuda Green 3.5-inch 2TB SATA 6 Gb/s Drive (64MB Buffer,5900RPM): Amazon.co.uk: Computers & Accessories
If you have any better suggestions in that size/price bracket feel free!
Had issues clearing the current 1TB HDD... tried to DBAN the thing but it wasn't playing the game for whatever reason. Anybody know any good programs for completely restoring a drive to as close to it's factory capacity as possible? I want to start completely afresh but I have a feeling Dell have done something which makes the partitions a bit dodgy or whatever. DBAN didn't recognize any of the other 4 parts, it saw the HDD though. I don't get it ^^
That's an update for now, case comes at 17:00-18:00 so stoked for that. Salvaged the fan in the Dell too, i should add.. more cooling = win!
Planning to add some colour fans to the setup too, red + blue specifically with filters to reduce dust.
