What's a modular PSU?
I'm looking at PSU's on Scan, I'm fine with buying the one brinks kindly linked as it's a Pro series but I was hoping For a 600W + There's three I can't decide between though.
The Sharkoon WPM500 500W Modular (PSU) which is £40.20
Sharkoon WPM500 500W Modular Power Supply (PSU) - Scan.co.uk

The Powercool PC650UM 650W Modular PSU which is £41.58
Powercool PC650UM 650W Modular Power Supply (PSU) - Scan.co.uk

And the ZCool PS-08 700W Modular (PSU) which is £40.67
EZCool PS-08 700W Modular Power Supply (PSU) - PS-890 - Scan.co.uk

What I can't really understand is a 700W PSU is only 47 Pence more expensive than a 500W one?

Can't decide between two cases: The Fractal Design Core 3000 Mid Tower Case = £47.98 Or the Corsair Carbide 200r which is roughly the same price.

As was said those are all terrible units. As I've said before myself don't substitute quality for wattage as a 700w PSU is just as likely to blow under a 300w load due to bad materials. Stick with the Corsair CX 600 if you really want more than 550w which isn't needed.

Can't compare two SSD's.
Intel 330 Series 60GB SSD costing £60
Or a Sandisk 64GB SSD which is £45
Quite a significant difference in price and more bang For less buck?
And does anyone know a good Case Fan manufacturer? I'm going to buy two extra 120mm Fans For my PC but I don't want to end up buying some really cheap Fan that will brake in a Few months.

Sandisk is cheaper because they make terrible SSDs.

Scythe make some good case fans. Their Kaze and Gentle Typhoon lines are good. The Corsair case fans are pretty decent too.

Noctua make some of the best fans around but they are super pricey.
