We have an existing homepage. I'll go through the elements one by one
Header - we want this part completely reimagined.
Logo - Either keep or redesign our logo. For redesigns, our site has nothing to do with PC's, so please nothing cute like making the 'O' a monitor or anything like that. Another option is to replace the logo 'PC Wholesale' with the letters 'PCW' (similar to how Computer Discount Warehouse is more well known as CDW).
Other elements - I think the graphics for our USP benefits (free shipping for orders over $100, lifetime warranty, 100% in-system tested) could be either different or eliminated. We would want to keep the benefits in the header, or at least somewhere else on the site. We want to keep the phone number prominent. I think we could also move the search box into the header, and therefore have a smaller "wrapper" for our content pages, if this could be done without de-emphasizing the search feature. Currently only a small percentage of people use it but they convert at a high rate.
My favorite web convention right now is the header with the stretching edges, while all the content remains in the center. A couple great examples of what I mean are http://www.vology.com and http://www.internetmarketingninjas.com.
Featured Clients - this must stay in place at the top of the site right under the header.
Left nav - must be in the final design, but the titles of the different categories could be changed, maybe have a section "memory" and below it have the manufacturers (cisco, dell, hp, ibm, sun) and then the remaining ones all still individual. I think it currently is a little wordy repeating memory over and over, but it is clear.
Center image - this is completely up for change.
Paragraph and Specialty block - I think this content is super good. It could be moved however.
Best sellers - I think this is also good. Could be moved or minimized.
How can we help and trust blocks - these need work. I think this space could be utilized way better. The content there is good (we need to have all the trust elements somewhere, and having the sort of 'sitemap' of top level categories and pages is necessary) but this whole part could definitely be sharpened up and made to look more slick.
