Hit up your secondary school use D&T room?
Can change your casing to Lian Li with side window?
Its not cheap to cut. If you do not have any tools, it will cost even more to cut that hole.
Your chassis is at around $6x. Doing the mod without proper tools will cost more than your chassis. Giving shop to do also will charge even more.
Rather you take all that money and get a better chassis.
Most of the chassis with windows are as low as $55. One good example Cooler Master 311. Does not justify to cut a hole for your chassis.
Other than that is the risk involve. Partly there is a reason why uvinium actually close down. Do you wanna bare all the risk if the shop does not do the job properly? Or damage your chassis? Or would you push the blame to the shop?
Not as easy as one can imagine if without proper tool.
Post some pics after you are done, ok?ive got my acryllic... arts friend... but now the cutting of case... im thinking of using tin snips,,, will it be alright
