First impressions are of a simplistic site with a professional logo and a neat navigation menu. Those happen to be the best things about it, but alas I don't come empty of suggestions and improvements. There's plenty of opportunity here.
First of all, the main menu is quite good even as it is although its vertical size may require people who still use resolutions lower than 1280x1024 to scroll down for the lower menu items. However, it doesn't fill the full width of the sidebar leaving the sidebar border hanging and creating an impression of unnecessary clutter. Fixing this may be a simple matter of adjusting the paddings and width of the drop down menu widget. The border of the sidebar could also be removed. It may be worth experimenting with this, but the idea is to tie up all the loose ends and have everything nicely aligned.
Also regarding the sidebar, the search box on it is too wide to fit within the borders of the sidebar so it sticks out. If the border were to be removed this would be fixed. Otherwise the search input box should be reduced in width.
The main menu seems to display categories and in sub-menus the articles in those categories. This leads me to expect that clicking on the category itself would list all articles in it, but instead it lists only one of them which can get confusing. Perhaps it's not a major issue given that all articles are apparently shown in the menu itself, but it's worth noting. Displaying all articles as drop downs only may also lead to an issue of not all articles fitting the screen and scrolling while keeping the drop down open can get tricky.
Another issue is that it is easy to confuse article titles and titles of sections within those articles in the homepage teasers because the two look too similar to each other. For instance for a bit I thought that "Xbox Live Features" was a title of an article when on a closer look (and a hover with a mouse over the real title link) reveals that this is just a section title, but the actual article is "Free Xbox Live Codes". This issue also adds to a perceived clutter of the homepage as the article and section titles on the homepage interchange with irregular distances. There is also no distinction between the introductory text and the articles.
Making article titles larger than the section titles (which are currently the ones which are larger) and changing their color to something distinctively different would already be of much help. Additionally teasers could be restricted to display only the introduction and no further sections which would make them display even more neatly on the homepage.
Speaking of teasers I noticed that below the teaser for "Free Xbox Live Codes" it says it has 3 comments, but clicking on that reveals no comments on the article page, just "Login to post comments". It's possible that anonymous users don't even have the permission to read the comments, not just view them, which I would venture to guess isn't the intention of the administrator. Otherwise displaying the number of comments seems unnecessary.
Speaking of the article page, the square ad that displays on it has a too low margin between it and the text around it. The result is that it looks more crammed, especially when the image ad displays when it almost touches the letters of the text. Also, the square ad below the article could be styled to fit the colors of the site or at least the colors of the sidebar ad.
All this said, it may be worth experimenting with additional improvements to the design. It might be a little too bare. Perhaps some sort of a distinction between the main content area and sidebars could be added in addition to the fixes mentioned. Maybe a header could be made more exciting. An introduction text could be put in a nice box. Something could be put in the footer which is currently empty.

Focus:
While the name Symatech reveals only the tie to technology the introduction makes an attempt at describing the site. There is also a slogan "We help make your life simple" which could either refer to the fact that technology tends to make lives easier or the focus of the site to making complicated things sound simpler. Unfortunately the introduction leaves something to be desired in terms of connecting with the slogan.
In any case looking at a sample of articles and categories it seems to be a general technology resource that dives in a little deeper into more advanced areas such as cryptography, databases, programming, UNIX and so on. Whether it is a general resource or there really is a specific approach or bent to the type of content that can be found should be briefly clarified in the introduction.

Content:
More than 200 articles are available via drop down menus some of which explain certain subjects in technology and others additionally offer practical guides to doing something such as deleting cookies from a web browser. They often use bullet lists and are split into sections. It almost seems like a small encyclopedia of technical information as it covers such advanced things as types of memory (like DDR2 SDRAM), types of storage interfaces (like RAID or ATAPI), networking systems (TCP, DNS, SSH etc.), UNIX commands and so on. So it can be helpful for someone looking to become a little more tech savvy.
Content Rating: 10/10
Symatech.net is simplistic, perhaps too much so, in terms of design where it could use some fine tuning and improvement, but quite advanced in terms of its content and subjects it covers acting almost like a small encyclopedia of technical subjects. Its introduction could do a little better in describing the focus of the site as well.
