Not a company I have seen before. Looks no bad.
I have always done mine myself. Its the best thing ever doing!
Same here, I have always enjoyed the thrill of getting all the parts and getting my area prepared to put it all together. I do recommend for anyone who is planning on and is new to building pc's to check out a few (don't just watch one, look for no less than 3 minimum) youtube videos on building, and do some research on spec websites to see what experts say. I have been building computers for 20 years and I will still keep my main pc up so if I come across something that just doesn't make sense I can look it up.
Other than that, just have fun and always, ALWAYS, have a friend on speed-dial that knows what they are doing lol.
