Kev are you thinking of buying online or at a local shop/computer fair.
If online i will look for a good value one (Uk myself)....if shop or fair then there are so many different makes/brands most are very similar inside you cannot make too much of a mistake when buying one...just make sure it will take a ATX motherboard inside it.
Sorry for the delay (long day at work) i went to CCL Computers 1st as i buy alot of products of them (i live near) but i have also bought online off them (they take telephone orders to) and cannot fault them !,i have included a link to the price list Here look under the section > Cases < then have a look at the Nokia style ones i have used these many times and they have given me no problems in the past....they are well built and the PSU is fine.
Also there are photos of the cases and you will be able to see where additional fans can be fixed. Also they stock the nokia cases with transparent side doors which comes with an additional cooling fan on the door...all that for £36.45 (Transparent door)(Non Transparent door £27.19) +£5.50 delivery.
They come in either silver or blue, if you do not like any of those listed i will have a look else where.
I have bought from E-Buyer before and all went very well (not bought any cases) from what i can see looking at there cases under the title "entry level midi" is that they are very cheap and look ok....plenty to look at !!....some look very similar to the budjet cases i have bought in the past from computer fairs and nearly all have been fine.
I do not expect the PSU to be great at that price but you can only try it and find out..yes
ive used scan.co.uk quite a few times for various things. never bought a case from them, because they tend to be a bit ugly imo (diff people have diff thoughts though). also, ive bought from http://www.ctech2000.co.uk - not the nicest looking site, but its not far from where I live and I've bought a few things from them. Final shops I know of are http://www.acemobilecomputers.co.uk (good lads who run the shop - its by my mums house in liverpool - prices are sometimes a bit steep but its worth looking) and also check at http://www.dabs.com
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
