The best fan for this is the article cooler 12 pwm or the nzxt
Both have white blades and black bodies blend well with the color theme.

Gt fan would look horrible in the color theme

the noiseblocker i think will move more air slightly but its also noiser.
their 140mm really moves a far bit more than the 120mm. Have them in my ldpc.

Noiseblocker fans are opaque grey thoughout
so i guess the front panel you are using 2 pcs of 120mm.

Just buy new drill bit. Aluminium 1-2mm needs about 1 minutes to drill with a new bit
buy the brand evacut just get it from the bolt and nut shop near monash
should be about rm3-4 each
and then you can a buy a m6 drill to do the countersunk for the csk screw

bear in mind brass will turn color once its oxidize. Will turn blackish

carbide bits are for stainless steel
and normally will also break, compared to HSS bits carbide bits break easily as they are much harder and less ductile as they are meant to be harder than stainless steel
A HSS drill bit can actually take some lateral force while drilling around 10degree and still will not break

if you using a hand drill, carbide is a no go as a slip can break the bit. However they don't blunt easily
DO note any drill bit will go blunt when working with plexi or even wood.

as mention buy industrial drill bits like evacut or Sandor, they cost around rm3 from screw shops and reputable hardware shops

carbide is mainly for stainless steel this are slightly yellowish
bench drill just buy HSS they are meant to drill normal steel, make sure you buy the branded stuff which cheaper than the cheap hardware store stuff from china
If you buy from a screw shop or a proper machine shop then the bits are important stuff from NZ or UK, or even germany
a evacut brand new HSS drill takes 30 seconds to drill m4 hole on a 1.5mm Stainless steel. and about 2 minutes on a blunt bit to cut thru 1.5mm stainless steel.

most people are not aware that you are not suppose to use high rpm while drilling. RPM for most drill just set around 800rpm as its the most versatile for small bit. Too fast it would blunt the drill bit, there is a chart you can follow. As the bit diameter increases you are suppose to drill at a lower speed. High speed above 1000rpm is meant for small size like m2 and m1 where the speed dictates the acuracy

1.8 for picture bookah
you can see the focus sharp and the rest blur

i bought from niclasteoh before
not sure it still has it do check
