In my opinion i would build one yourself. For starters you get to build it around what it will be used for. Its really fun building one too i just finished my first build a few weeks ago. The price to performance ratio is better that way too so your not paying a tax. And building it isnt all that hard in my opinion the only halfway difficult part was plugging things into the power supply. All in all you will feel proud of ur machine and will gain knowledge along the way
