Hi all,
this is my first build, and i need something quite specific. I have chosen all of the components already, but would like an external point of view.

First, the vital questions :
- any obvious mistake? (it's my first build, i might have forgotten something vital)
- will all my components work fine together ?

And then the extra ones :
- is this build well balanced? (it's a waste to have a very expensive powerful component, along with a cheap crappy component that will slow everything down)
- will it do what i need?
- are there better/cheaper components that i could have chosen?

Let me start with the exciting part : the components that i have chosen
Then, i will answer a few questions about what my needs are.

My choice now :
What | my choice | price (£)
CPU : i5-2500S (65W) - 130.00

Mobo : Gigabyte GA-H77N-WiFi - 80.00

PSU : picoPSU-160-XT + Univ 192W AC Adapter - 103.00

Case : M350 enclosure - 55

Fans (x 5) : Fractal D. 40mm Silent Series - 5 x 5.5 = 27.5

2nd Hard Drive/Fan Bracket for M350 - 3.50

CPU cooler : Akasa 7106 HP - 10

SSD : Vertex 3 (120GB) - 90

RAM (x 2) : Corsair Vengeance Low Profile 2x8GB - 60

TOTAL COST : £537.00 (+ shipping)

And now, i answer a few questions to explain you what my needs are :

1. What will you be doing with this PC?
=> i don't play games at all, i don't use Photoshop.
I want to run 4 Virtual Machines (VMs) simultaneously, each of them running Windows XP or Debian. And each of them using Firefox to go on internet and do basic things, like using spreadsheets. One of the machines (or maybe the 4 of them) will also run a program that i'm making. It doesn't do much though, so i don't need something very powerful.
So, the main thing i want to be able to do is to run 4 VMs simultaneously, and i don't want to be slowed down when i do basic things.

From what i read, to get fast VMs i need lots of RAM, and fast a fast hard drive. That is why i chose 16GB RAM (1600MHz), and a fast SSD drive.

Also, i don't need much storage space : no music, no game, no pictures, no videos, etc.

And i need the Wifi !

2. Will you be overclocking?
=> no.

3. What's your budget?
=> not more than £700

4. Where do you live? (Are there computer shops around?)
=> London.

5. What exact parts do you need for that budget?
=> I don't need a GPU. I think that i need :
Processor, Mobo, PSU, Case (mITX thin), CPU cooler, SSD 60GB x 2, RAM, Case fans

7. What specific features do you need in a motherboard?
=> I want SATA 6Gb/s x 2, and USB 3.0 (required)

8. What resolution output do you need?
=> i want to use two monitors. If possible with DVI or HDMI

9. Does this system need to fit into a particular space?
=> i want it very small and lightweight, as i will need to move it every few months (to use it at a friend's)

10. How comfortable are you with custom case design/modification and electrical wiring? What tools do you have.
=> not very comfortable but i can learn. I don't have tools.

11. How important is the noise/silence of this sytem?
=> i want it as quiet as possible. I work in a shared office, so i don't want to annoy other people with noise. And noise gives me headaches, too.

12. How mobile does this system need to be?
=> see question 9.

13. Do you already have a legit and reusable/transferable OS key/license?
=> yes, 3 x WinXP

14. When do you plan on building/buying the PC? Immediately, in a couple weeks, 3-5 years?
=> within a couple of weeks, as soon as i feel confident enough that i have made good choices.

For starters, delete all of those links. You aren't allowed to link to competitors.

You'd also be better off posting this in the General Hardware forum area. That's were the majority of 'spec me' threads go. ;)
 
Your case and PSU add up to £158, if you went for something like this InWin:
http://www.overclockers.co.uk/showproduct.php?prodid=CA-023-IW&groupid=2362&catid=2279&subcat=
which comes with a PSU then you would save £108 and could go for an i7-3770 CPU which would give you 8 threads and even better performance running multiple VMs. The S CPUs only save 11W (65 vs 77) and with the rest of your configuration you'll still have plenty of headroom powerwise.


My main machine for running VMs is a 8-core AMD box with 16GB - soon to be 32GB - RAM but I'm running multiple server OSes on that so it's a much bigger load than yours would be but I'd still say get as many cores and/or threads as you can :)
 
You'd be much better off going for MATX rather than ITX. It will cost about the same and give you 4 ram sockets and some extra PCI-E sockets for NIC/RAID cards in the future. RAM is far more important than CPU for VM's, I wouldn't want to be limited to 2x8gb sticks.

What hypervisor or OS are you looking to use? HyperV, VMWare Workstation or ESXi, Virtual Box? You shouldn't really be deciding on hardware until you know.
