bleh... I think it looks horrendous as well... how large are the ones in the pictures? and apply it on a case...
also, apart from the performance tiered systems from OEM's, they never have big blatant logos like that... and never in sticker form unless its a case badge which is also rare... they are usually emobssed/etched/painted on... so i don't think its that similar
I second the case badge movement, you can contact iandh on overclock.net (not sure if he'll help you... but try?) since he has access to some machines that can make case badges... Cyberdruid (heard of him? famous for some sick mods and great waterfall reservoirs) got him to make his badges!
edit:
hey a bit of advice (not trying to be offensive or anything...) about your site
A) The header needs a bit of work... the font looks bad... its barely legible gets pixelated at such high sizes and why is the background base color white? its off the sites main colors....
B) Don't ask for people to donate to a business... that is ridiculous! 'Hey you bought a PC from us! Want to throw us some extra money so that we can make some more dough?' Instead offer tiered warranty services, custom services to the computers... or you could start up some sort of an upgrade policy for donating members or something...
C) Take the eCommerce site offline (at least for non-admins) it really confuses first time buyers about whats happening even if you have an update message... it also hurts first opinions about your business if people see a broken ecommerce site as the 'Store'
D) You need to update the side/navigation bar... my recommendation if you plan to regularly update/change the site is to move to a CMS system... get away from the HTML site (if thats what it is) since those take a whole lot of work to update... try Joomla, PHP-Nuke etc.
If you don't want me to comment here... then I can edit it and PM you
GL with your business! I've always wanted to do something like this! Once you get ready, you should try getting some cheap text ads on google so that you can expose your site!
Finally... lol, mind PMing me some more information about your business? I'd be interested to know what your working fees are... how you stock items if you do etc.
