Re-Build Computer


Likes # 0

Evening, right I don't even know where to start ehehe but here it goes... In 2006 I built a computer which would last me at least 5 years, it's now almost 6 years, and poor little guy is struggling...

The thing is, I use to know quite a bit of computers hardware and software, but this was 6 years ago... recently I found out that manufacturers don't do any more parts to desktop... which lead me to a trip to the unknown...

I'm completely lost, Motherboards, drives, cables, everything is looking more and more from the twilight zone for me (yes I'm getting old too).

I know there's a budget for everything including build a PC from scratch like mine but since mine is quite old I just want to upgrade it so I think I wont need to spend a big amount of money (like £1000) since it might be easy to find some parts... I don't want it for gaming or so but mainly I need it touse AutoCAD (don't know if you recognise this software but involves 2D and 3D drafting, with lots of rendering)...

I would like to ask you guys that are definitely more experienced then I am, what Motherboard, Drives, etc would I need to get to achieve this. I'm not asking a top of the charts piece of hardware but more like near the bottom parts but better then what I've got.

Can you help me with this?

Nice case and PSU, but I think you realise that you could have made savings with case and PSU. This from a man who spent £120 on a case decided I did not like it after a couple of months so then spent £200 on a replacement.

Keep us posted as you get your components, I had better remind you that do not forget the thermal paste. Pain in the rear if you come to assemble and the vital part is missing.

As you say you use your computer mainly for Autocad, which is very heavy on the processor and memory, I would suggest you bite the bullet and have a look at the Apple Mac range, as they are more suitable for the work you do.

Keep the old one for other purposes or sell it as you wish.
